Best Grilled Cheese Ever

Directions

1. 1
   Begin by roasting the chiles over the flame on your stovetop (or under the broiler) until the skin is totally blackened (if using fresh).
2. 2
   When the chiles are totally charred, throw them into a plastic bag.
3. 3
   Seal and allow them to steam and cool.
4. 4
   Next, pour the white vinegar over the sliced red onion and let them sit awhile.
5. 5
   This'll take away a little of the crazy onion flavor and leave them with a nice sweetness.
6. 6
   Finally, make the special sauce: equal amounts of mayonnaise and Dijon.
7. 7
   It's the simple things in life!
8. 8
   When you're ready to make the sandwiches, scrape the blackened skin off the chiles.
9. 9
   Scrape out the seeds, too, so you'll wind up with big pieces of roasted green chiles.
10. 10
    For each sandwich, generously spread 2 pieces of rye bread with the special sauce.
11. 11
    Lay on 2 slices of provolone, 2 slices of tomato, 2 slices of Cheddar... a nice layer of roasted green chiles... a few red onion slices... and one more slice of provolone just to hold it all together.
12. 12
    Top with the other slice of bread and spread the outsides with a good amount of butter.
13. 13
    Toast the sandwich in a skillet over medium-low heat until the cheese is thoroughly melted inside.
14. 14
    Be careful not to burn the bread!
