as
@Lou suggested oatmeal is so versatile, you can add lentils to it, fruits, nuts, toppings of seeds, spices etc
morning smoothies are also great - froz berries, banana, some greens if you like, plant milk, and I add spices like turmeric/pepper and cayenne and a bit of salt as I find it satisfies me for longer
lunches - I am not a huge salad fan so I often throw some frozen veggies and noodles in water and once cooked I pour it over a half a can of drained lentils and then put on some lemon juice, tamari, rice vinegar, tahini and sweet chili sauce
soups are amazing anytime because you can add all the ingredients you like or have available - try to do a mix of onion/garlic, basics like carrots, celery, broccoli, kale, add some potatoes and/or sweet potatoes and then a can of beans and a can of chopped tomatoes - use some veggie stock or miso and all the spices you love - make a huge pot and you can have it for many meals and add more as you go if you like - you can sub pasta or rice for the potatoes and add all differents kinds of veggies like, parsnips, zucchini, cabbage, squash, mushrooms, and so on...
