Begin by preheating your oven to 350°F (175°C). This will prepare a warm environment for your sandwiches to be reheated later.
In a large, non-stick skillet, heat 1 tablespoon of olive oil over medium heat. Add the baby spinach to the skillet and sauté for 2-3 minutes, or until the spinach is wilted and tender. Once done, remove the skillet from heat and set the sautéed spinach aside.
In a separate bowl, crack the eggs and whisk them together. Season the egg mixture with a pinch of salt and black pepper for flavor. Pour the whisked eggs into the same skillet, allowing them to cook over medium heat. Scramble the eggs gently until they are fully set and cooked through. Once cooked, remove the skillet from heat.
While the eggs are cooking, toast the split English muffins in a toaster or under a broiler until they are golden brown and slightly crispy.
To assemble your breakfast sandwiches, take the bottom half of each toasted English muffin and layer on the following ingredients in this order: sautéed spinach, scrambled eggs, slices of avocado, halved cherry tomatoes, and a sprinkle of your chosen shredded cheese.
Close each sandwich by placing the top half of the English muffin over the filling.
For storage, wrap each individual sandwich tightly in aluminum foil. This makes them convenient for future use and helps to retain moisture.
Store the wrapped sandwiches in the refrigerator for up to 5 days or in the freezer for up to 1 month.
Notes
For an extra kick, serve with a drizzle of hot sauce on the side!
