Toast 8 frozen waffles according to package directions until lightly golden. Let cool slightly.

Cook 8 slices of bacon until crispy. Drain on paper towels.

Slice 1 ripe avocado.

For each sandwich, layer one slice cheese, 2 slices bacon, one quarter of the avocado and a second slice cheese between two waffles.

Spread the total 2 tablespoons mayonnaise thinly over the outsides of the four sandwiches.

Heat a large skillet over medium-low heat.

Place the assembled waffle sandwich in the skillet and cook for 3-4 minutes, pressing down gently with a spatula, until golden brown and crispy.

Carefully flip and cook for another 3 minutes until the second side is golden and the cheese is completely melted.

Remove to a cutting board and let rest for 1 minute.

Cut in half diagonally and serve immediately.

Repeat with remaining waffles to make 4 sandwiches total.
