Stuff I had in the house: tuna, mayo, salt, pep, rye bread, cheddar cheese, pimentos, onion.
Slice an onion and saute in a little olive oil on med-low for about 20 minutes until caramelized. yum!
Then, butter one side of the rye bread. Place in same pan you cooked onions and top with shredded cheddar cheese:
Top with caramelized onion and pimentos:
Mix tuna with mayo (to taste), salt, pepper. Add to sandwich, top with more cheddar cheese.
Top with other buttered bread slice.
Cook until browned on both sides.
Warm, gooey, cheesy, tasty! The caramelized onions are nice and sweet, and the pimentos add a nice twist. It was a pretty quick, I-don't-feel-like-cooking weeknight dinner!
