This dish is a basic recipe for baking summer squash. The lack of milk makes it less custard-like. The recipe following makes it into a custard.
Steam until tender four to five cups of sliced summer squash - yellow, zucchini, pattypan. Lightly mash or leave in whole slices. Saute half a small onion. Mix squash, onion and 1 cup grated cheese with two beaten eggs. Varying the flavor of cheese can make entirely different dishes. Try goat cheese, Gruyere, smoked Gouda or even Habanero jack. Season with fresh chopped herbs of your choice. Dill, basil and thyme all taste delicious. Salt and pepper to taste. Put in an oiled casserole and bake uncovered at 350 for 30-40 minutes. You can sprinkle with Panko or wheat germ before baking for a crispier crust.
