These savoury salami bites are an easy appetizer made by crisping salami slices in muffin tins to form edible cups, then filling them with a fresh, bruschetta-like mixture of cherry tomatoes, kalamata olives, cucumber, feta cheese, and pickled red onion, seasoned with olive oil, red wine vinegar, salt, pepper, and chili flakes. A 10/10 easy appetizer!
