I have a few really quick go to meals.
Stir fryCan't get much easier. I always have tofu in the house. Chop tofu and brown in a little olive oil with garlic and ginger. In another pan or same pan but remove tofu, stirfry any veggies you have. I am having Kale and mushrooms with onions tonight. Add whatever seasonings (soy sauce etc.) and put on top of brown rice. I always have extra cooked brown rice in the fridge.
note-If I do not have tofu just substitute another protein and pair with appropriate veg. I will use nuts like raw almonds or walnuts. If so I like celery and mushrooms with nuts on the brown rice.
Pan StewSome olive oil in the pan and cook onions, garlic, and some vegetables like peppers, celery, kale -whatever really. I add 'just like ground' and if you are okay with canned vegan gravy go for it if not make your own sauce and pour on top of russet boiled/mashed potatos or rice.
I use 'just like ground' quite a bit, more then I would like actually as it is a processed food. But I like it.
I think the tips above are great too. As long as you cook up a grain and have veg and protein on hand you have a meal. I make veg shepard's pie with the just like ground too. And as stated above by others you can soak and cook up a pile of beans on the weekend for the week to use as your protein.
