• 2 tbsp heavy cream

• 1/4 tsp salt

• 1/8 tsp black pepper

• 1 tbsp mayonnaise or keto-friendly sauce (optional)

• 1 handful of fresh spinach or arugula (optional)

• Hot sauce or sriracha to taste (optional)

Instructions

 

Step 1: Prepare the Bread Substitute

For Egg Buns (Omelet Style):

1. In a bowl, whisk the eggs, heavy cream, salt, and pepper until well combined.

2. Heat a non-stick skillet over medium heat and melt 1/2 tbsp butter.

3. Pour in half of the egg mixture and swirl to coat the bottom of the pan evenly.

4. Cook for 2–3 minutes until the egg is set, then flip carefully and cook the other side for 30 seconds.

5. Repeat with the remaining mixture to make two egg “buns.” Set aside.

For Chaffles:

1. Preheat your waffle maker and grease it lightly with butter or coconut oil.

2. In a bowl, mix the egg, shredded cheese, almond flour, and baking powder until combined.

3. Pour half of the mixture into the waffle maker and cook for 3–4 minutes until golden brown.

4. Repeat for the second chaffle. Let them cool for a minute to firm up.

Step 2: Cook the Protein

1. In the same skillet, cook the bacon slices or sausage patties until browned and fully cooked. This usually takes 3–4 minutes per side on medium heat.

2. Set them on a paper towel-lined plate to drain excess fat.

Step 3: Assemble the Sandwich

1. Place one egg bun or chaffle on a plate.

2. Add a slice of cheese on top.

3. Layer the cooked bacon or sausage patty.

4. Add sliced avocado, spinach (if using), and mayo or sauce for extra flavor.

5. Top with the second egg bun or chaffle.

6. Optionally, return the assembled sandwich to the skillet, cover with a lid, and heat gently for 1–2 minutes to melt the cheese.

Step 4: Serve

• Let the sandwich rest for 1–2 minutes before serving to allow the ingredients to set and meld.

• Slice in half for easy handling and presentation.

• Serve with a side of fresh berries or a keto smoothie for a complete breakfast.

Tips and Variations

• Make it spicy: Add jalapeños or hot sauce for a kick.

• Vegetarian option: Skip the meat and use grilled mushrooms or extra cheese for a hearty filling.

• Meal prep tip: Make multiple egg buns or chaffles ahead of time and store them in the fridge for up to 4 days or freeze for longer.

• Add variety: Swap in turkey sausage, ham, or even leftover steak for a different flavor profile.

• Cheese layer upgrade: Try gouda, Swiss, or pepper jack for more gourmet taste.
