I typed "low carb casseroles" into Google search and came up with this idea. I totally changed the original recipe to suit me and what I already had. I call them, "Pop Up Omelets".
Ingredients can easily be changed to suit you, too. (Sorry my "inside" photos' color is a little off. I'll remember that for the next time)
POP UP OMELETS
10 eggs, whisk good (I removed 5 yokes)
1/4 cup Jalapeno Peppers, chopped (I used jarred)
1/2 cup cooked sausage (I used veggie sausage)
1 1/2 cups any shredded cheese
salt and pepper to taste.
Stir together, pour into oiled muffin pan and bake at 375 for 30 minutes. Makes 9 omelet poppers.
These can be frozen. To eat, just pop into the micro wave. Yumm with fresh fruit.
