Prepare the Ingredients: If using roasted jalapeños or red peppers from a jar, drain and remove seeds. Crumble the feta cheese into chunks for easier blending.
Blend: In a food processor or blender, combine feta, roasted peppers, jalapeños, olive oil, lemon juice, and garlic (if using). Blend until smooth and creamy.
Adjust Seasoning: Taste and add salt, pepper, or extra lemon juice as needed. For a chunkier texture, pulse instead of fully blending.
Serve: Transfer to a serving bowl. Drizzle with a little extra olive oil if desired. Serve immediately with pita bread, crackers, or vegetables, or use as a spread or topping.
Store: Refrigerate in an airtight container for up to 7 days. Re-blend slightly if texture thickens.
