Add the torn lettuce into a large salad bowl.
Dice the roma tomatoes down the middle and then into quarters.
Dice into bite-sized pieces. Repeat with the cucumber. (Peel the cucumber if desired
before dicing for an extra fancy touch.) Add diced vegetables into the bowl.
Slice the red onion into very thin slices and add to the bowl.
Remove the pepperoncini peppers from the jar and drain well. Add to the bowl.
On a cutting board, lay out the pepperoni and prosciutto. With a sharp knife slice into ribbons and add them to the bowl.
On the cutting board, drain the candied tomatoes and marinated artichokes from the olive bar. Chop them into bite-sized pieces and add to the bowl.
Using your fingers or a slotted spoon, remove the mozzarella from the oil marinade and drain excess oil off the cheese. (You want a little oil still on the mozzarella for moisture, just not the whole bowl.) Add all the mozzarella to the bowl.
Finish with freshly sliced basil leaves for garnish if desired.
Dress with your favorite Greek salad dressing, toss well before serving.
