Creating the Havarti Avocado Sandwich with Spicy Mayo is a breeze. Follow these simple steps:

1. Prepare the Spicy Mayo: In a small bowl, mix mayonnaise and Sriracha until you reach your desired spice level. Taste and adjust as needed.

2. Avocado Preparation: Cut the avocado in half, remove the pit, and scoop the flesh into a bowl. Mash it with a fork, adding salt, pepper, and lemon juice for flavor.

3. Toast the Bread (optional): Preheat a skillet or toaster. Lightly toast the bread slices until golden brown for added texture.

4. Assemble the Sandwich: Spread a generous layer of spicy mayo on one slice of bread.

5. Add the Avocado: Spread the mashed avocado evenly over the mayo layer.

6. Layer the Cheese: Place the Havarti cheese slices on top of the avocado.

7. Add Greens: If using, layer fresh cilantro or spinach leaves over the cheese for added nutrition and crunch.

8. Top It Off: Place the second slice of bread on top to complete the sandwich.

9. Slice and Serve: Cut the sandwich in half for easier handling and serve immediately.

By following these instructions, you will create a flavorful sandwich that is both satisfying and easy to make!
