These little fruit and ham sandwiches are nice for a picnic or potluck.
In a bowl combine mustard, olives, and parsley. Spread the cut sides of 12 roll tops with olive-mustard mixture. Place ham on the roll bottoms. Top ham with mango slices (cut slices to fit, if necessary) add olive-mustard spread bun tops. Makes 12 sandwiches (using 2 ounces cooked meat per sandwich).
