35 minThis is the sandwich that leftover turkey was born to become.
Spanish onions get the full caramelization treatment: sliced thin, cooked low and slow with garlic, thyme, and a pinch of sugar until jammy and golden.
A splash of white wine vinegar at the end gives them a bright edge that cuts right through the richness.
Stack those sweet, sticky onions onto whole wheat bread with generous slices of turkey, melty Swiss, and a smear of sweet mustard.
Press it in a panini press or grill it in a skillet until the bread is crispy and the cheese is stretching.
Chef Tips
- Patience is everything with the onions. A full 20 minutes on medium-low turns them from sharp and raw to sweet and caramelized
- Butter the outside of the bread for the crispiest, most golden crust when grilling
- No panini press? A heavy skillet pressed on top of the sandwich in another skillet works just as well
- This works beautifully with leftover Thanksgiving turkey, deli turkey, or even rotisserie chicken

In a large nonstick pan or skillet, heat both oil and butter over medium-low heat.

Spread unbuttered side of 4 of the slices with mustard.
Top with onion mixture and 6 ounces each turkey and swiss cheese.
Top with remaining bread, buttered side out.
Grill in skillet over medium heat, or in panini press, until browned and cheese is melted.
