Step 1

Slice the rolls lengthwise, cutting only half way through. Remove the thick, fluffy dough center of the bread and discard it. Set rolls aside.

Step 2

In a small bowl whisk together the vinegar and oregano; slowly add in the oil, whisking as you pour to emulsify the mixture.

Step 3

Drizzle a small amount of the oil/vinegar mixture on the rolls, then layer the cheese and meats.

Step 4

Top with the tomatoes, onions, lettuce, then peppers. Drizzle with additional oil/vinegar, cut in half, and serve!
