Melty Patty Sandwich (Print Version)

# Ingredients:

→ Patty

01 - A pound of ground beef
02 - One big onion, sliced super thin
03 - Season with salt and pepper as you like

→ Assembly

04 - Four slices of cheddar cheese
05 - Butter for browning on the grill
06 - Eight slices of rye bread
07 - Four slices of Swiss cheese

→ Secret Sauce

08 - A half cup of mayo
09 - Two spoonfuls of ketchup
10 - One spoonful of sweet pickle relish
11 - A teaspoon of Worcestershire sauce

# Instructions:

01 - Stir mayonnaise, ketchup, relish, and Worcestershire in a small dish. Put aside when blended.
02 - Heat a tablespoon of butter in a big pan over medium. Stir onions now and then as they cook down and brown over 15-20 minutes. Set them aside after they're ready.
03 - Shape the beef into four flat patties and sprinkle with salt and pepper. Using the same pan, cook them over medium-high heat, flipping after 3-4 minutes each side. Put them aside for now.
04 - Spread butter on one side of the bread slices. Stack like so: bread (buttered side out), Swiss cheese, cooked patty, caramelized onions, cheddar cheese, bread (buttered side out). Grill each side until bread's toasty and cheese melts, around 2-3 minutes.
05 - Wait about a minute before cutting the sandwiches into triangles. Add the sauce on the side or drizzle over the top.

# Notes:

01 - Swap with ground turkey or chicken if you want a lighter choice
02 - Feel free to switch out the cheese types
03 - Try plant-based patties to make it vegetarian
