A veggie burger is certainly a healthier choice than a real meat burger. Having said that I still believe a homemade veggie burger would be far better than the store bought processed one. I treat these foods, as in processed vegan foods, as a treat. Maybe for a special occasion or something, but I definitely don't make it a regular thing.
I can help a bit with some ideas to keep on hand for quick meals. I've found YouTube to be my best friend with information on how to make do without oil. Salt is not so hard for me, but the oil is something I struggled without in the beginning. I was used to frying everything. Since I've stopped using excessive amounts of oil, I not only feel better, but my arthritis has gone completely away. I also stopped eating all sugar, with the exception of about a tablespoon of maple syrup on my oatmeal in the morning and the odd stir-fry (sauce). Some people even go as far as using a super ripe banana to sweeten their cereal instead of the maple syrup.
So the thing I try to do is make enough food preparation for a meal that will leave enough leftovers for another the following day....soups, stews, chili, to name a few. Humus is also easy to make (can be delicious oil free) and lasts a few days in the fridge. It makes a great snack food with some celery sticks, crackers, whatever.
I love rice and beans, which can evolve into different meals as leftovers. Like from a simple bowl of rice & beans topped with salsa, to a rice & bean taco topped with avocado and fresh mango.
I really enjoy sushi veggie rolls. They're quite easy to make. Sushi rice comes together fairly fast, after the rinsing process. Sushi rice must be rinsed really really well, but aside from that it cooks fast and makes delicious fast meals once cooked. It really is best used up the same day, but I've used day old sushi rice before. It's doable. Anyhow, check out Youtube if you want to learn how yourself. The fillings can vary from yummy avocados, yams, shredded carrots, daikon radish, cucumber, asparagus, and so on.
The trick is to always think ahead, but if you want something really fast, just freeze some leftovers that can be microwaved or reheated in the oven at a later time. One meal I do enjoy from frozen is a simple bag of frozen veggies (I like the Asian blend) sautéed up in a wok style frying pan with a delicious homemade sauce. No oil is needed, but you need a lid for your frying non-stick frying pan.
So toss the frozen veggies into your frying pan (wok), add a wee bit of water or vegetable stock, and I mean a wee bit. I also add some fresh minced ginger and garlic to give it a more authentic taste. Cook it on medium high with the lid on for about 8-10 mins or until desired tenderness. Just before they're done, you can add your sauce, and cover and finish. The sauce is simply maple syrup and soy or soy like alternative. If you know how much corn starch, you can mix that into the sauce at this point, but I prefer to make a corn starch and water solution and thick it at the very end. Sprinkle with some toasted sesame seeds and viola, dinner is served. I don't often have leftovers with this one, as I don't usually make rice or noodles, but if you wanted to stretch this out into a couple meals, just make some rice or rice noodles to accompany it.
It might sound really hard, but try to work your way up to a eating more whole plant-based foods. So opposed to eating the olive oil, have the olives instead. Have coconuts, but not coconut oil. Remember, just because it's not fried or has oil in it, doesn't mean it won't taste good. You just need to find good recipes and adjust your diet to living this way. Youtube for me has been so helpful in learning to cook without oil. It's useful for a lot of very delicious recipes, perioid. There are channels dedicated to cooking vegan without oil. I like this one "
HERE" , but there's many more if you look.
I will make an exception once in a while. You know, like when you dine out, or for special occasions, holidays, etc.
If you want to know why I don't do oil, you can thank Dr. Esselstyn for that..."No Oil!" so he loves to say. Check his video out. My mom died at 59 from a heart attack. My brother just died a couple years ago from colon cancer. I had my reasons for going vegan. It was mostly for health reasons, I am not ashamed to say, but I am happy to no end to not contribute to the torture and killing of animals for food.
Sorry for the long rant, but hopefully it's helpful.
