Pulse feta cheese, olive oil, lemon juice, pepperocini salad peppers, garlic, oregano, dried crushed red pepper, and black pepper in a food processor 6 to 8 times or until combined, stopping to scrape down sides. Cover and chill 2 hours before serving. Store in refrigerator up to 3 days. Serve warm or cold with warm pita bread. Garnish with dried crushed red pepper and olive oil, if desired. I have mixed with a large fork.
