Healthy Gluten Free "Fake" pizza - no bread

How about a pizza without bread and with a whole bunch of protein?

For 2 Fake pizzas

2 chicken fillets
2 ripe tomatoes
1 pepper (color of your choice)
2 cups spinach
1/2 cup low fat feta cheese
1/2 cup banana peppers
1/4 cup onion
fresh basil (optional)

1. Preheat oven to 400°F. Working one at a time, place a chicken cutlet between two layers of wax paper (or plastic wrap). With a meat pounder, pound the chicken pieces to flatten them to an even thickness - between 1/4 - 1/2 inch. (If you don't have a meat pounder, you can use a rubber mallet, an empty wine bottle, or a heavy rolling pin.) Salt and pepper the chicken pieces well.
2. Cook the chicken fillets in a pan until almost don.
3. Salsa: Chop tomatoes, peppers and onion finely and mix together (add Basil if wanted)
4. Place the chicken fillets in a baking dish, cover them with a layer of fresh spinach, add the salsa and add feta cheese on the top. Bake in the oven for 10minutes.
