Over the weekend I squeezed in family time, a live Scooby-Doo show in Manhattan, some mall shopping with my teen, a play date at Bounce-U, and we celebrated my brother’s birthday. I also made a quick run to Target — I love browsing seasonal decor, but this time I only picked up new flatware, dishes and napkins in a bright coral pattern to brighten the kitchen until spring really arrives.
Back to breakfast: this egg-white omelet is a light, satisfying option. It has the fresh sweetness of tomatoes, melty part-skim mozzarella for creaminess, and a little grated Parmesan for savory depth. My husband joked it tasted like a breakfast pizza — next time I’ll add fresh basil and call it a Margherita omelet. It’s low in carbohydrates, rich in protein, and takes about ten minutes from start to finish.

A fast, light omelet that combines juicy tomatoes, egg whites and two cheeses for a breakfast that’s both flavorful and low in carbs.
Prep: 5 mins Cook: 5 mins Total: 10 mins
Yield: 1 serving Serving Size: 1 omelet
Ingredients
- 1/2 tsp olive oil
- 1/4 cup sliced grape tomatoes (or diced cherry tomatoes)
- Salt and pepper, to taste
- 1/3 cup liquid egg whites
- 1/4 cup shredded part-skim mozzarella
- 1 tsp grated Parmesan cheese

Instructions
- Heat a small nonstick skillet over medium heat until hot.
- Add the olive oil and the sliced grape tomatoes. Season with a pinch of salt and a few grinds of black pepper.
- Cook the tomatoes about 1 minute, just until they begin to soften and release some juice.
- Pour the egg whites over the tomatoes, spreading them evenly in the skillet.
- Sprinkle shredded mozzarella and the grated Parmesan over the egg whites.
- Cover the pan, reduce the heat to low, and cook until the egg whites are completely set and the cheese is melted, about 2–4 minutes depending on your skillet and stovetop.

Tips and Variations
- Margherita style: Add torn fresh basil on top for a classic tomato-mozzarella-basil flavor.
- Make it heartier: Add a few sliced mushrooms, baby spinach, or diced bell peppers when you sauté the tomatoes.
- Different cheeses: Try part-skim ricotta for creaminess or a sprinkle of reduced-fat feta for tang.
- Cooking method: If you prefer, bake this in a small ovenproof skillet or ramekin at 350°F until set, about 8–10 minutes.
- Meal prep: Multiply ingredients to make multiple omelets at once; keep cooked omelets in the fridge and reheat gently in a skillet or microwave.
Why this works
This omelet uses egg whites for a lean source of protein while keeping the cheese and fresh tomatoes for flavor and texture. The quick sauté softens the tomatoes without overpowering them, and covering the skillet ensures the egg sets evenly while melting the cheese.
