Courtney's Spinach Brownies/Spinato's Squares

2 TB butter
1 TB veggie oil
2 TB sugar
1 medium to large sweet onion, chopped
4 cloves garlic, chopped
2 10 oz packages frozen chopped spinach
1 cup all-purpose flour
1 ts salt
1 ts baking powder
2 eggs
1 cup milk (I've used soy, whole, and skim...all seem to work fine)
1/4 cup butter, melted
1 8 oz package mozzarella cheese
1 package bacon bits (or 1 cup if cooking your own bacon)
4 Roma tomatoes, sliced

Preheat oven to 375; grease a 9"x13" pan.

Carmelize the onions. You don't HAVE to do this, but I prefer the sweet onion to be sweeter; it makes it seem like there aren't onions in the dish. Melt 2 TB butter and veggie oil in a pan on medium-low heat and add onions. Reduce heat to low, cover, and cook for 15 minutes. Uncover pan, sprinkle with sugar, stir thoroughly, and continue cooking on low, uncovered, for 25 minutes. I shake the pan/stir the onions occassionally. Add the garlic the last 5 minutes of cooking.

Put the spinach in a microwave-safe bowl and cook for about 7 minutes to thaw. Add bacon and set aside.

In a separate bowl, add the flour, salt, baking powder, eggs, milk, and melted butter. When the onions and garlic have finished cooking, add them to the bowl, along with the spinach, bacon, and mozzarella (reserve a little bit of the cheese to sprinkle on top of the tomatoes). Pour into baking dish and arrange the sliced tomatoes on top, sprinkling them with the remaining cheese.

Bake for 35 minutes.
