Notes
If you’re starting with uncooked veggies, use the following measurements and instructions:
1 lb Brussels sprouts (about 3 cups trimmed and cut in half)
1 lb butternut squash (about 4 cups chopped)
On a baking sheet, drizzle veggies with 2 tablespoons olive oil and season with salt and pepper. Roast veggies in oven at 400 degrees F for 35 minutes or until tender. Add to cast iron.
To check if the frittata is set, pierce the middle of the frittata with a knife and if the eggs run, cook longer.
