Whole Wheat Flour. The whole wheat flour in this recipe adds a little bit of texture to the breakfast pie and can be substituted or left out.
Substitutes for Whole Wheat Flour. Use a one to one replacement of white flour or almond flour (for gluten-free).

Storing and Using Leftovers
As with many casseroles, this one tastes better after a day or two, so be sure to make extra. Leftovers can be stored in the refrigerator or freezer.
Refrigerate leftovers in an airtight container for up to four days.
Freeze cooked leftover veggie egg casserole in a freezer-safe container for up to three months. Defrost the leftovers in the refrigerator overnight.
