I make tofu quiche sometimes and have adapted it to be lowfat (I make it 
 without any crust these days).  Here’s the recipe:
 Tofu Quiche <T>
 1 Tbsp corn starch
 1/2 cup skim milk 
 1-2 eggs' worth of egg substitute or 2-4 egg whites
 1/2 cup fatfree or lowfat cottage cheese (I use 1%)
 1/2 cup fatfree plain yogurt
 1 cup reduced fat tofu (Mori Nu Lite), cubed
 salt and pepper to taste
 dash or 2 Tabasco sauce
 Put the above ingredients in a blender and puree till smooth.  Stir in (not 
 using the blender :) ) 1 or more of the following:
 1/2 cup chopped onion, sauteed in liquid of choice
 1/2 - 1 cup chopped fresh mushrooms
 1 cup chopped cooked broccoli, spinach or leeks
 1/2 cup fatfree mozarella cheese
 herbs to taste (parsley, basil, marjoram are all good)
 Pour into quiche dish or pie pan sprayed briefly with Pam and bake at 
 350 F for 30-40 min or until a toothpick inserted slightly off center 
 comes out clean.  Let stand about 5 minutes before serving.
 Sometimes this comes out watery (like custard sometimes does), but it 
 still tastes good.
