My family loves breakfast food any time of day. Breakfast, brunch, or “brinner”, it’s always good! I try to ask for input from my kids for meal ideas, and my son’s most frequent dinner request (besides pizza, or course!) is “brinner.” And why not? Breakfast foods are usually cheap, nutritious, fast, and easy to make. If we can eat cold pizza for breakfast, surely some eggs would be OK for dinner, right?
Eggs are an incredibly versatile food, that sometimes get a bad rep. However, I like to include them during weekly meal plans as they are a cheap source of protein. Each egg contains about the same amount of protein as an ounce of meat at about half the cost. But, that’s not the only benefit of eggs. Eggs are also a source of many vitamins and minerals such as vitamin B12, folic acid, selenium and choline.
This recipe is quite adaptable and can be made in a variety of ways to accommodate different tastes. The cheddar cheese, for example, can be switched out for some Swiss, mozzarella, or feta. The peppers and onion can be omitted (for picky kids perhaps?) or even swapped for some spinach, mushrooms, tomatoes, or any combination of vegetables you prefer. Sometimes I will even add diced ham for a more savory flavor. I do, however, recommend against adding high fat meats such as bacon or sausage. In my personal experience, the dish becomes greasy and soggy, and is just not appetizing.
This is my favorite recipe to make for holiday mornings, like Christmas and Easter. I make the dish the night before, cover in foil, and store in the refrigerator until morning. Once morning comes this goes straight from the fridge to my (unheated!) oven. It’s a great way to provide a healthy, hot breakfast for my family while still being able to participate in the holidays. My kids prefer to have fresh fruit and muffins as side dishes, but toast works just as well. Leftovers? No problem! This reheats nicely for a quick breakfast on busy work or school mornings.
