When it's cold out, my go-to meal is chicken soup. I usually have the veggies and broth on hand, as well as cooked or raw chicken in the freezer. If the chicken is already cooked, then the meal comes together in less than 30 minutes.
We also will often do breakfast for dinner. Eggs of some kind (scrambled, omelettes, etc.) with fruit and veggies.
Sausage (can use turkey sausage), peppers, and onions browned and cooked in the IP or oven is pretty quick and easy.
Bean and cheese burritos (with either cooked beans that I keep in the freezer or canned) with fruit and veggies.
