For breakfast, lunch, or dinner, each slice of this veggie-studded egg casserole is super satisfying. Because it’s a make-ahead dish, it’s convenient when you have little time to spare to get a meal on the table. Chunks of crusty bread soak up some liquid to give the casserole a heartier texture. But try to give the precooked casserole some time in the fridge—the flavours will mingle together and the bread will have a chance to soak up some of the liquid. Not into bread? You can replace it with frozen diced hash brown potatoes. For the richest flavour, use half-and-half or whole milk. But you can also use lower-fat milk or unsweetened dairy-free milk if desired. Consider serving with your favourite salsa and/or avocado slices.
Protein power: Yes, food inflation has also hit the egg carton, but the orbs are still good-value protein—each large egg supplies about 6 g of complete protein. Beans have been enjoyed by numerous cultures for centuries as an ultra-nutritious plant-based protein that fits into all budgets.
