Sprinkle the cheese over the bottom of the pie shell, then evenly distribute the onion, broccoli, and mushroom over the cheese layer. Mix the eggs and the spices together in a bowl. Add the milk and half-and-half and mix well. Pour over contents in the pie shell.
Cut the cherry tomatoes in halves and place, cut side up, in a ring on top of the mixture. Sprinkle the 1 tablespoon of Romano over top. Bake for 15 minutes. Turn oven down to 300 degrees F and bake an additional 45 to 55 minutes or until cake tester inserted in middle comes out clean.
Sheila's Never Fail Pie Crust:
Blend together with pastry blender until crumbly (like coarse cornmeal). Add cold water, 1 tablespoon at a time, mixing with a fork until mixture will hold together. Handle as little possible. Wrap in plastic wrap in a "patty" and chill for at least an hour. Roll out between Saran Wrap with very little flour. Place carefully in a pie plate, being careful not to stretch dough. Trim the edges.
