Creating a Breakfast Sandwich Platter is simple if you follow these steps:

1. Prepare the Ingredients: Gather all your ingredients and chop the vegetables (tomato, spinach, avocado) as needed.
2. Cook the Bacon or Sausage: In a skillet over medium heat, cook the bacon or sausage until crispy. Remove and set aside.
3. Fry the Eggs: In the same skillet, add butter or oil. Crack the eggs into the skillet and cook to your desired doneness (sunny-side up, over-easy, etc.). Season with salt and pepper.
4. Toast the Bread: While the eggs are cooking, toast the slices of bread until golden brown.
5. Assemble the Sandwiches: Spread mayonnaise on one side of each slice of toasted bread. Layer on the cheese, spinach, tomato, cooked bacon or sausage, and eggs.
6. Top It Off: Add sliced avocado on top and finish with another slice of toast.
7. Serve: Cut the sandwiches in half for easier handling, and arrange them on a platter.

By following these straightforward steps, you will have a delicious Breakfast Sandwich Platter ready to enjoy!
