My new favorite blog, Sally's Baking Addiction, recently featured a low calorie version of a crust-less quiche. Needless to say I made some in my tart tins and the result was tasty and light.
Recipe link here.
-I sliced up some yellow squash, zucchini, yellow onion, and garlic, and sauteed them until soft in olive oil over medium heat.
-I whisked together 3 whole eggs plus 3 egg whites, milk, salt, and pepper.
-In another bowl, I grated small hunks of sharp cheddar, havarti, parmesan, and gouda cheeses, and mixed it in with the egg/milk mixture.
