1 cup cooked, finely chopped mixed vegetables, drained or squeezed of any excess liquid (I use leftovers from other meals like spinach, zucchini, mushrooms, etc…)
1 tbsp minced onions
2 eggs, at room temperature
1/2 cup liquid egg whites, at room temperature
1 cup “milk” (soy, flax, rice, cow: all work)
2 tbsp “flour” (sorghum, oat, garbanzo bean, whole wheat, etc…)
1 tsp mixed herbs and spices (I like to mix tarragon, thyme, black pepper, and nutmeg – 1/4 tsp of each)
1/4 tsp cream of tartar
1. Preheat the oven to 350 degrees. Grease a casserole dish 7 inch in diameter and 3 inch in height with your favorite method (olive oil, vegan butter, etc…) and coat the dish well with bread crumbs. (I use Ian’s gluten free bread crumbs or make my own in the food processor with Udi’s gluten free bread.)
2. Mix the finely chopped vegetables with the minced onions and set aside. (Be sure to squeeze out any excess liquid from the vegetables.)
3. Separate the yolks from the whites of the two whole eggs, and add the yolks to the vegetable mixture. Add the whites to the liquid egg whites. You should have 3/4 cup of egg whites for your use.
4. In a large, shallow pan, mix the milk with the flour and herbs and/or spice choices, whisking well to incorporate the flour and seasonings into the milk.
4. Cook the milk mixture over medium low heat, stirring continually, until the mixture begins to thicken. Should only take about five minutes in a large, shallow pan.
5. Stir the vegetable mixture into the sauce and allow the mixture to cool slightly.
6. Put the liquid egg whites into a clean mixing bowl and stir in the cream of tartar. Using the wire whisk attachment to your mixer, whisk your eggs until the whites double in size, are foamy and white, and when you pick up the whisk, the eggs are stiff, tilting to a 45 degree angle.
7. Slowly add the egg whites to the vegetable mixture, incorporating a little at a time, using a curve spatula and moving gently in an S motion, around the edge, down the center, until all the egg white is mixed into the vegetables.
8. Gently spoon the souffle mixture into your prepared dish, and carefully tap the dish once or time to level it.
9. Bake in the preheated oven for about 40 minutes. The souffle will have risen and be puffed, dry and firm, no longer wet.
10. Remove and serve immediately.
