Zucchini & Yellow Squash Quiche-ish

It isn't really a quiche, but I didn't know what else to call it, to be honest...  My mom was coming to visit for the weekend, and she got stuck in traffic for over an hour...  I knew she would be ready to eat when she finally made it and she's usually game for trying something new - plus she likes squash!

Ingredients
1 medium-large zucchini, halved and sliced
1 large yellow squash, halved, seeded and sliced
1/2 of a small red onion, diced
2 Roma tomatoes, sliced
4 eggs (We get a dozen of Dry Dock Farms fresh eggs each week, so this was a no-brainer!)
1/4 c olive oil
1 tsp baking powder
1 c baking mix (like Biscquick)
Grated parmesan
salt & pepper to taste

How to:
Preheat the oven to 350 degrees. Grease a 9-inch round baking dish.

Prepare your vegetables and add salt and pepper to taste.

Whisk together the eggs with the oil until they are nice and fluffy.  Mix in the baking powder and baking mix until it's combined evenly.  Then, fold the mixed vegetables into the egg mixture.  Pour into the baking dish and top with the tomato slices.  Sprinkle grated parmesan over the top, and place into the oven to bake.

Bake for 40 minutes, or until it starts to brown and eggs appear cooked through.

This was our main course, so it only served four big pieces...  And, I should have taken a picture before we dug into it.  But, we were hungry - it was 9:00 p.m.!  :)  I'll make this again, and may even try it with different vegetables.  It seems like any combination would work!
