- Eggs. Eggs have so many health benefits. For instance, eggs have more nutrients -- such as vitamins, minerals, amino acids -- per calorie than most other foods, are high in protein, help your good cholesterol and lower triglycerides, lower your chance of having a stroke, are heart-healthy, help your eyes, and sharpen your brain.
- Milk. I use 1% milk, but you can use almond milk, coconut milk, or oat milk.
- Shredded cheese. I use white cheddar cheese, but you can use your favorite kind. It would be great with sharp cheddar, gouda, swiss, mozzarella, or even feta.
- Diced ham. Ham goes great in an omelet, just make sure it is already precooked. You could also use bacon, thinly sliced cooked steak, cooked sausage, leftover chicken, or salmon.
- Mushrooms, bell peppers (I used green, yellow, and orange). You can also use spinach, tomatoes, and leeks. Look in your fridge and use up anything that you have sitting in the crisper.
This omelet is easy to modify to suit your tastes. Are you a vegetarian? Leave out the meat. Do you want to make it healthier? Add more vegetables. The sky is the limit for what you can do with this baked oven omelet.
