• 1 large onion, thinly sliced
• 2 tbsp olive oil

How to Make It

1️⃣ Grill the Steak

Preheat your grill or grill pan to medium-high heat.
Season both sides of the steak generously with salt and pepper.
Grill for about 4–5 minutes per side for medium-rare, or longer depending on your preference.
Let the steak rest for 5 minutes, then slice thinly against the grain for the most tender bites.

2️⃣ Caramelize the Onions

While the steak is resting, heat olive oil in a skillet over medium heat.
Add the thinly sliced onions and cook for about 5–7 minutes, stirring often until soft and starting to turn golden.
Add the butter and balsamic vinegar, and continue cooking for another 5 minutes until the onions are beautifully caramelized and jammy.

3️⃣ Toast the Bread

Lightly grill or pan-toast the bread slices until golden and crispy on both sides.

4️⃣ Assemble the Sandwich

Spread a little mayo on one side of each slice of bread if you’re using it.
Layer on the sliced steak, then pile on the caramelized onions.
Top it all off with a slice (or two!) of provolone cheese and close the sandwich.

If you want it extra melty, pop the assembled sandwich back on the grill or under a broiler for 1–2 minutes to let the cheese ooze!
