Instructions
Make the Maple Mustard Sauce
- Whisk syrup, mustard, and mayo until smooth. Stir in thyme and cayenne if using. Set aside to let flavors develop.
Cook the Protein
- Bacon: Start in a cold pan, cook over medium 7–10 mins until crisp.
- Sausage: Cook patties 3–4 mins per side until browned.
- Vegetarian: Follow package instructions until heated and golden.
Scramble the Eggs
- Whisk eggs, milk, salt & pepper. Melt 1 tbsp butter in a non-stick pan over medium-low. Gently stir eggs with a spatula until soft, creamy, and just set. Remove from heat.
- Toast the Croissants
- Slice croissants in half. Brush with melted butter. Toast cut-side up at 350°F for 2–3 mins until lightly golden.
Assemble
- Spread sauce on croissant bottoms.
- Add greens (if using), then eggs, cheese, and your protein of choice.
- Add avocado slices, extra sauce on the top half, and close the sandwich.
- Wrap for neat eating—optional but handy!
Notes
- Make Ahead: Scramble eggs and cook protein ahead—reheat gently before assembling.
- Vegan Swap: Use tofu scramble, vegan sausage, dairy-free cheese, and mayo.
- Gluten-Free Option: Use gluten-free croissants from a specialty bakery.
- Custom Flavors: Swap thyme for rosemary or sage, and try different cheeses like Havarti or Fontina.
