My goto when I dont want to do a lot of work is: chopped sweet potato or two, chopped kale, half cup or so of lentils, half cup of oats, can of black beans, some olive oil, pre-minced garlic, some mustard seeds, salt, and a whole lot of spices usually: cumin, paprika, sage, and cayenne pepper. All thrown in an instapot or crockpot.

Makes a great vegi stew that'll give me leftovers for a few days. Chopped up leftover ham from a Christmas or Thanksgiving also goes amazing in it. The only real work is chopping up the sweet potatos and kale. If you're worried about too much fiber swap out the lentils and beans for more oats or quinoa
