Instructions:
- Slice grilled tri tip thinly against the grain. If not warm, heat briefly in a skillet until just warmed through.
- Heat olive oil in a skillet over medium heat. Add onions and optional bell peppers. Sauté for 10–12 minutes until soft and caramelized. Season with salt and pepper.
- Toast the sandwich rolls or buns in a dry skillet or on the grill until lightly crisp.
- Spread mayonnaise or garlic aioli on the inside of each bun, if using.
- Layer the warmed tri tip on the bottom halves of the rolls.
- Top with the sautéed onions and peppers, then place a slice of cheese over the top.
- Transfer sandwiches to a warm oven or under the broiler for 1–2 minutes, just until the cheese melts.
- Top with the remaining bun halves, garnish with fresh parsley if desired, and serve immediately.
Variations :
- Swap provolone for Swiss, mozzarella, or smoked gouda for a unique cheese twist.
- Add sautéed mushrooms or a smear of horseradish cream for an extra layer of depth.
- Use ciabatta rolls or baguette slices for a more rustic texture.
Tips :
- Always slice tri tip against the grain for maximum tenderness.
- Prep components ahead of time—tri tip and onions reheat beautifully for quick sandwich assembly.
- Serve with warm au jus, steak drippings, or a side of coleslaw for a full plate experience.
