For the roasted onion and olive topping:
1 small red onion, ends removed and cut into 8 wedges
1/2 cup pitted kalamata olives
1 tablespoon olive oil
For the dip:
8 ounces Greek feta cheese
4 tablespoons olive oil
4 tablespoons red wine vinegar
1 cup full fat milk
1 red chili pepper, minced
1 clove garlic, minced
Make the topping: Preheat your oven to 400 F. Toss onions and olives with oil on a small baking sheet. Roast for 5-7 minutes, until the onions just begin to soften. Remove from heat and set aside to cool.
To make the dip, add all dip ingredients to food processor and pulse until smooth. Spoon into a serving dish. Top with onions and olives and drizzle with additional olive oil, if desired. Serve immediately.
