I'm pretty new too.
As for what I eat. I can say it is far more varied now than when I used to eat meat and dairy...
Tofu, Tempeh, Various soya-based substitutes, lots of mushrooms... Button, Portabello, Shiitake, Oyster etc.
Lots of mixed nuts
Seeds (add to salads)... Pumpkin, Sunflower kernels, sesame, pine nuts etc
Nutritional yeast...add to most casserole, curry, etc type dishes
Lots of fruit and veg (and we grow a lot of our own such as Pak Choy, tomatoes, cucumber, red berries, raspberries, black-currants, gooseberries, apples, blueberries)
beans, lentils(make a great substitute for Taco night minced beef.)
I make lots of curries, pasta dishes, taco night dishes, risotto, Paella etc
Or get some tofu and apply batter and fry
Or Tofu scramble...add nutritional yeast, turmeric and black salt for a very nice scrambled egg alternative
Vegan pizza...Either use a store bought vegan grated cheese or make some cashew "mozzarella"
Lastly, I sometimes do the lazy thing and put on some Beyond burgers!
