Potluck surprise: Orzo and veggies with ricotta cheese

Is there any better venue for Sunday lunch than an awesome church potluck? We had some 500 people show up today for a party to help christen our beautiful new facilities at St. James Church in Wichita. And everyone brought excellent food.

I was among parishioners alphabetically assigned to bring a vegetable dish. I got up early this morning and made up this recipe; wasn't sure how it would turn out, but it was good, and I'm happy to report there wasn't much left by the end of the party:

Zucchini , spinach and tomatoes with orzo, ricotta and basil

15 ounce container of ricotta cheese
2 eggs
1 cup orzo
2 cloves garlic, crushed
1/4 cup chopped fresh basil
4 small zucchini , sliced
2 small yellow squash, sliced
7 medium tomatoes, diced
1/2 cup plus 3 tablespoons freshly grated Romano cheese
1/2 pound fresh spinach leaves
Olive oil

Cook orzo according to package instructions. In a medium bowl, while pasta cooks, combine ricotta cheese, 1/2 cup Romano cheese, eggs, basil and garlic. Mix well. Rinse cooked pasta and drain. Add to ricotta mixture.

Brush a 9-by-13-inch casserole dish with olive oil. Place a layer of zucchini in the bottom of the casserole dish. Top with 1/2 of the ricotta/orzo mixture. Top with half the spinach, a layer of zucchini and tomatoes, then add remaining ricotta/orzo mixture. Top with yellow squash and the remaining zucchini, spinach and tomatoes. Top with 3 tablespoons grated Romano cheese. Bake at 350 degrees for 45 minutes. Remove from oven. Brush top lightly with olive oil. Bake for another 10 minutes. Salt and pepper to taste.
