Tandi's Tomato Pie

this is from country living. Tim and Julia love tomatos so it thought i would give it a try. it remindes me of pizza.

4 med. tomatoes
1 pie shell, baked
1 c. chopped onion
1/2 t. salt
1/2 t. pepper
2 T. fresh basil (i put in 2 t. basil, and will do slightly less next time.)
1/2 c. mayo
1/2 c. parmesan cheese
1 c. shredded cheddar cheese.

Cut 6 tomato slices for garnish. halve remaining tomatos, removes seeds, and cut each half into 6 wedges. place half of the tomato wedges into the bottom of the baked pie shell. sprinkle with half the onion, salt, pepper, and basil. mix mayo, parmesan, and cheddar cheese together and spread half over the onion layer. repeat in the same order starting with tomatos. place sliced tomatos on top in a pinwheel design.

bake 375 for 30-40 minutes until golden
