Slice an onion and 2-3 red, orange, or yellow peppers and place them in the bottom of a 9x13 pan. (Slice the onions thinly so they cook through.)
Cut 2-3 thawed chicken breasts in half and lay over the onion and peppers. Drizzle with olive oil.
Bake uncovered at 400 degrees for 20-25 minutes until the chicken is done.
Top with slices of mozzarella cheese and broil for a minute or two just to brown the cheese.
I usually serve this with quinoa, which is also fast and easy. Once I get the chicken in the oven, I have just enough time to get the quinoa cooking and have it all ready at about the same time.
Saute in a bit of oil or butter:
1/2 cup chopped onion
minced garlic clove
1 cup quinoa (Rinse well unless the package says it is already rinsed.)
2 cups water
1/4 tsp salt
1 small carrot, grated (optional)
Bring to a boil, reduce heat and simmer covered for 15 minutes or until all the water is absorbed. Quinoa much more forgiving than rice; it doesn't get sticky or gooey and has a great flavor. Quinoa is high in protein, calcium, and more. If you've never tried it, go for it!
