Hi Tera and welcome.
I agree with Birgit, soups make a great meal-in-a-bowl for one. Make your soup with rice or whole-wheat pasta, beans and or other protein, and keep in the fridge or freezer in single portions.
Casseroles are also great for that...and super easy to heat up when you get home from work or the gym.
Also, keep cooked brown rice, quinoa and/or whole-wheat pasta cooked, and packed in portions for one...you can always add steamed veggies, pan-fried tofu, tempeh or seitan for a quick and healthful meal.
