Holy genius husband!
I love it when Eric gets out this appliance for dinner.
I love it even more when it involves using leftovers. I have quite a few glass and clear containers so that I cannot forget about the contents. I am known to allow leftovers to ferment far longer than is healthy.
Tonight he took sliced bread and topped it with cheddar cheese and a mixture of leftover Butternut Squash Pasta Bake mixed with fake beef crumbles.
Then he added a large dollop of mayo and spread it evenly on both sides.
Place on preheated waffle iron, press closed, and cook until light changes from red to green.
Seriously, who needs a panini grill? He made a second one with Norwegian caramelized goat cheese, called Gjetost and it was even better. I could live off these bad boys.

The sandwich was delicious with the Gjetost!
My other favorite waffle sandwich is PB&J french toast.
