This assembly-only snack is the perfect party make-ahead!
In a heavy-bottomed saucepan, combine the olive oil, orange juice and zest, garlic clove, rosemary, chili flakes and salt, and bring to a simmer over medium heat. Cook for 1-2 minutes to allow the spices and herbs to soften; set aside.
Drain the olives and add them to the warm olive oil mixture. Let sit for at least 15 minutes to soak up the flavors.
