Once everything is cooked, it’s merely a matter of layering the ingredients on toasted English muffins for a delightful hand-held treat.
What You’ll Need
Gather the following items to make this delicious breakfast sandwich:
- Cooking spray or 2 teaspoons olive oil
- 1/2 white onion – diced
- 5 oz fresh spinach
- 6 large eggs
- 4 egg whites
- 1/2 teaspoon kosher salt
- 1/4 teaspoon ground black pepper
- 1/4 cup milk
- 1/4 cup shredded cheddar cheese
- 1 cup sliced cherry tomatoes
- 6 English muffins – sourdough or whole wheat
- 6 cheddar cheese slices
Note: You can swap out the English muffins for your preferred type—whole grain or even gluten-free options work beautifully!

Directions to Follow
- In a skillet over medium heat, add cooking spray or olive oil. Sauté the diced onion for about 3-4 minutes until it’s translucent and soft.
- Toss in the fresh spinach and cook until it wilts. Set it aside.
- In a large bowl, whisk together the eggs, egg whites, kosher salt, black pepper, and milk until well combined.
- Pour the egg mixture into a lightly greased baking dish. Gently fold in the sautéed veggies and shredded cheese. Bake in a preheated oven at 350°F for about 25-30 minutes, or until the eggs are set. Let cool before slicing.
- Toast the English muffins. Layer each muffin half with the baked egg squares, cheddar cheese slices, and sliced cherry tomatoes. Top with the other half of the muffin and serve warm.
Best Ways to Enjoy It
Serve your Healthy Breakfast Sandwich warm and fresh. Pair it with a side of seasonal fruit for a burst of sweetness or a refreshing glass of orange juice. For a touch of heat, drizzle with your favorite hot sauce, or try a dollop of avocado spread for a creamy contrast.
How to Store
If you have leftovers, storing them correctly is essential. You can keep the sandwich components separately in the refrigerator for up to 3 days. The baked egg mixture can be sliced and stored in an airtight container, while the English muffins can be kept in their packaging. For reheating, simply warm in the microwave or place in a toaster oven until heated through.
Tips to Make It Perfect
- If you like a bit of spice, consider adding some diced bell peppers or chopped jalapeños to the sautéed veggies.
- Experiment with different cheese types for a unique flavor twist—pepper jack, feta, or even a vegan cheese can work beautifully.
- Ensure that the baking dish is greased well to prevent the egg mixture from sticking.

- Veggie Lovers: Add more vegetables like bell peppers, zucchini, or mushrooms to the mix.
