1 cup frozen peas, thawed
1/4 cup fresh mint leaves, stems removed
2 tablespoons water
1 tablespoon olive oil
1/2 teaspoon black pepper, divided
1/4 teaspoon kosher salt, divided
1 (8 ounce) baguette, halved lengthwise
2 ounces thinly sliced prosciutto (could substitute baked ham)
1/2 cup very thinly sliced red onion
3 medium tomatoes, thinly sliced
3 ounces provolone cheese (or cheese of your choice)
Place peas, mint, water, oil, 1/4 teaspoon pepper, and 1/8 teaspoon salt in the bowl of a food processor. Process until smooth.
Hollow out the bottom and top halves of bread, leaving a 3/4 inch think shell.
Spread pea mixture evenly over the cut sides of bread; evenly layer prosciutto, onion, tomatoes and cheese. Sprinkle with remaining salt and pepper.
