Best-Ever Tri-Tip Sandwiches with Garlic Aioli

Add the mayo, garlic, lemon juice, salt, and pepper to a small bowl. Whisk until smooth.

Preheat the broiler on high. Let it heat for about 5 minutes while you make the sandwiches.

With a sharp carving knife, thinly slice the tri-tip against the grain. (If you're using leftover tri-tip, wrap it tightly in tinfoil and heat it in the oven at 325°F for 5-10 minutes until warmed through.)

Using a serrated knife, slice the rolls in half horizontally. Place all 8 halves on a sheet pan. Spread 1/2-1 tablespoon of garlic aioli on the cut side of each halve of bread.

Divide the tri-tip between the bottom half of each sandwich. Top the tri-tip with 2-3 slices of provolone cheese. Broil the sandwiches until the cheese is melty and the top half of the sandwich roll is a bit toasted.

Top the melted cheese with a handful of frizzled onions and a handful of arugula (about 1/2 cup each). Finish with sandwiches with the top of each roll. Slice in half and enjoy right away!
