Ingredients You’ll Need 🛒
These sandwiches use everyday ingredients, but the flavor combo makes them feel gourmet. Here’s a breakdown with extra tips:
- 2 teaspoons olive oil: For sautéing veggies. You can also use butter or avocado oil for richness.
- ½ cup chopped red onion: Adds mild bite and color — sub shallots for a sweeter touch.
- ½ cup chopped bell pepper (any color): Gives texture and brightness. Try a mix of red and green for contrast.
- 4 large eggs 🥚: Whisked into a fluffy, veggie-studded omelet layer.
- Salt, to taste: Don’t forget to season the eggs! A pinch enhances every bite.
- 1 tablespoon butter: Used to cook the eggs gently and toast the muffins — rich and flavorful.
- 4 whole wheat English muffins: Nutty, hearty base for your sandwich. Swap in sourdough, bagels, or croissants for variety.
- 4 slices sharp cheddar cheese 🧀: Bold flavor and perfect melt. Try gouda or Swiss for a twist.
- 4 slices cooked bacon 🥓: Crunchy and savory. Turkey bacon or plant-based strips work too!
- ¾ cup guacamole 🥑: Adds creaminess and a fresh finish. Use store-bought or homemade.
How to Make Breakfast Sandwiches 👩🍳
- Sauté the Veggies:
Heat olive oil in a nonstick skillet over medium heat. Add the red onion and bell pepper. Cook for 3–4 minutes until softened and lightly golden. Transfer to a bowl and wipe out the pan. - Make the Omelet Base:
Crack the eggs into a bowl, add a pinch of salt, and whisk until smooth. Melt the butter in the skillet over medium-low heat, swirling to coat the bottom evenly. - Cook the Omelet:
Pour in the eggs and scatter the sautéed vegetables over the top. Let sit for 1 minute, then gently lift the edges and tilt the pan so uncooked egg can flow underneath. Once mostly set, cover with a lid briefly to finish cooking the top. - Cut the Omelet:
Slide the omelet onto a board, fold it into thirds like a letter, and cut into 4 equal squares — one for each sandwich. - Assemble the Sandwiches:
Toast your English muffins and begin building:- Bottom muffin half
- Slice of cheddar
- 1 square of omelet
- 1 slice of bacon (halved to fit)
- Big spoonful of guacamole
- Top muffin half
- Serve Warm (or Freeze!):

Short version

Breakfast Sandwich
Ingredients
- 2 teaspoons olive oil for sautéing the veggies
- ½ cup chopped red onion for a pop of color and flavor
- ½ cup chopped bell pepper – use any color you like
- 4 large eggs cooked to your preference
- salt to taste added during or after cooking the eggs
- 1 tablespoon butter for toasting the muffins
- 4 whole wheat English muffins split and toasted
- 4 slices sharp cheddar cheese for a rich melty layer
- 4 slices cooked bacon for crunch and savory flavor
- ¾ cup guacamole to add creaminess and a fresh finish
Instructions
- Cook the veggies: Heat olive oil in a 10-inch nonstick skillet over medium heat. Add the chopped onion and bell pepper and sauté for about 3 minutes, until softened. Transfer the vegetables to a clean bowl and set aside. Wipe out the skillet.
- Make the omelet: Crack the eggs into a bowl, add a pinch or two of salt, and whisk thoroughly until fully combined. Melt the butter in the skillet over medium-low heat and use a spatula to spread it evenly over the bottom and sides.
- Pour the eggs into the pan and sprinkle the cooked veggies evenly over the top. Let the eggs cook for 1 minute. Once the edges begin to set, gently lift them with a spatula while tilting the pan to allow uncooked egg to run underneath. Repeat around the edges until the top is no longer wet.
- Lower the heat and let the omelet finish cooking until the top is nearly set. If needed, cover the skillet with a lid to help it cook through. Transfer the omelet to a plate or cutting board, fold it into thirds, and cut into 4 equal portions.
- Assemble the sandwiches: Split and toast the English muffins. Layer each with a slice of cheese, one portion of the omelet, a slice of bacon (cut in half), and a spoonful of guacamole. Serve immediately. (Optional: warm the assembled sandwiches without guacamole in a 350°F oven for 2–3 minutes to melt the cheese, then add the guacamole before serving.) See note for freezing instructions.
Notes
