Gather These Items
Here’s what you’ll need to put together this delightful 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
Consider using low-fat cheese to cut down on calories or swapping the English muffins for whole grain if you’re looking for a healthier option.

Directions to Follow
Cook the Veggies: In a skillet, heat the cooking spray or olive oil over medium heat. Sauté the diced onion until it becomes translucent. Next, add the fresh spinach and cook until wilted—this should take about 2-3 minutes. Set aside.
Prep the Egg Mixture: In a bowl, whisk together the eggs, egg whites, kosher salt, black pepper, and milk until everything is well combined.
Bake the Eggs: Pour the egg mixture into a greased baking dish. Bake in a preheated oven at 350°F (175°C) for approximately 20-25 minutes or until the eggs are fully set.
Build the Sandwiches: Remove the baked egg from the dish and slice it into squares. Toast the English muffins to your liking. Layer each muffin half with the sautéed veggies, a square of baked eggs, sliced cherry tomatoes, and a slice of cheddar cheese. Crown your creation with the other muffin half and enjoy your delicious breakfast sandwich!

Best Ways to Enjoy It
This Healthy Breakfast Sandwich is fabulous all on its own, but there are plenty of ways to elevate your dining experience. Serve it with a side of fresh fruit, a light salad, or crispy hash browns. For drink pairings, consider a refreshing green smoothie or a hot cup of herbal tea.
Keeping Leftovers Fresh
Storing leftovers? Simply place any remaining sandwiches in an airtight container in the refrigerator. They will stay fresh for up to 3 days. When you’re ready to enjoy them again, just pop them in the microwave or reheat in a toaster oven for a quick grab-and-go breakfast.
Tips to Make It Perfect
- To make the sandwich even more filling, consider adding slices of avocado or cooked turkey bacon.
- Use fresh herbs, like basil or dill, in your egg mixture for added flavor.
- Avoid overcooking the eggs; they should be soft but set when you pull them from the oven.

Feel free to experiment with this Healthy Breakfast Sandwich! You could swap out the spinach for kale or include roasted bell peppers for an extra pop of flavor. For a Tex-Mex twist, add some salsa and avocado. Alternatively, try using different types of cheese or whole wheat pitas instead of English muffins for a fun change.
