Banana burger

Yesterday I had a really unique pairing of flavors on my lunch sandwich, and wanted to share. T.G.I. Friday's has a "Chipotle Grilled Steak Sandwich". Nothing unusual about that.
"Tender Cajun–rubbed skirt steak served on toasted ciabatta with a blend of Colby and Monterey Jack cheeses, lettuce, tomato, onion & Chipotle mayo. Served with beer–battered onion rings."

Since I despise mayonnaise and tomatoes, I skipped both, but there's one very important flavor to this sandwich that I left out. Roasted plantains. Much more colorful and tasty than bananas, and it worked surprisingly well on the sandwich. If the steak was a little more tender it would be outstanding.
