I like to keep things simple. For dinner I sauté a veggie with olive oil, salt and pepper; pick a grain such as rice, polenta, farro; and a type of bean or legume.
Black beans and rice, peppers and onions on the side
Polenta topped with mushrooms, side of chickpeas
Bulgur mixed with chickpeas, herbs and cucumbers, side of broccoli
Farro with chickpeas and tomatoes, side of green beans
Lentils over rice, side of Brussels sprouts
I deconstruct for my young kids and they eat the portions of the meal they like, along with additional stuff (often string cheese or toast, lots of fruit).
I e been a vegetarian for 35 years and I don’t own a food processor or mixer so I think you will be ok
I don’t personally recommend any of the processed proteins like tofu or seitan or whatever trendy mock meat is current, but you may like something like the impossible burger.
I’m terrible at meal planning so this makes it easy for me!
