I am preop and have been vegan for a few years. I am planning on tofu scramble, refried beans, split pea soup, blended soups, blended lentils, chia pudding, soft tofu dishes and maybe cashew & cauliflower ricotta if I can tolerate it.
Try veggies/fruit that can be mashed (carrots, cauliflower, squash, bananas, apples, etc.). You could try mixing protein powder into applesauce, grits, oatmeal, or cream of wheat. There's vegan yogurt. What do you like to eat now?
I am on the preop diet now and I really like pea protein isolate blended into broth when I am tired of shakes. I like the Vitacost brand.
