Looks like you need more veggies and fruit. It is recommended to get 9 servings a day. Beans, nuts, and dairy can be good sources of protein. Whole grains are essential as well. Fiber is important for your digestive system, too.
If you're not much of a cook, I would suggest a kids cookbook from the library. They have cute meals that are simple to prepare and they can be healthy, too! For example, you can saute some zucchini, yellow squash, onions, garlic, dried basil, salt, pepper in olive oil. Add some whole wheat pasta or brown rice pasta, mix it up and then sprinkle some cheese over the top and close the lid for a minute while the cheese melts. Eat with a green salad and nuts and a side of fruit--you have a meal and then you can take the leftovers to work for lunch, etc.
Good luck!
