These marinated salmon bites make a quick crowd-pleasing appetizer. Pink peppercorns offer a bit of spice and a slightly floral flavor, but freshly ground black peppercorns work well too. (Since black pepper has a stronger flavor, you’ll need just a quarter of the amount.) This appetizer can be served with toothpicks and a light creamy sauce for dipping, or as a main dish served on a bed of brown rice. Leftovers can be used to top a green salad or stuffed into pita bread with lettuce and tzatziki for an easy sandwich.
