This high protein breakfast sandwich is low-carb, gluten-free, and loaded with protein and healthy fats.

An open-faced egg, sausage, cottage cheese, and avocado breakfast sandwich, topped with a drizzle of spicy mayonnaise, makes for a super-filling and satisfying meal.
Every time I make this sandwich for breakfast, I'm shocked at how delicious it is and how long I stay full after eating it.
I don't even want to snack after eating this protein-filled breakfast.

Whether you're a busy professional, a student on the go, or a parent juggling multiple responsibilities, incorporating a high-protein breakfast into your routine is essential for sustaining energy levels and promoting overall well-being.
You can also make this without the spicy mayo if you prefer not to add a spicy kick.

If you want to increase your protein intake, consider using a high-protein, low-carb bread, such as Unbun Protein Bread. Unbun Protein Bread is a low-carb, gluten-free option that provides 11g of protein per slice.
I used Base Culture Keto Bread because I could not find Unbun bread in any stores in my area.
