In a large bowl, combine ground meat, breadcrumbs, parsley, garlic, onion, oregano, cumin, paprika, and egg. Season with salt and pepper.
Mix until just combined, being careful not to overwork the mixture.
Roll into small bite-sized meatballs, about the size of a walnut.
Heat olive oil in a skillet over medium heat and fry meatballs in batches until browned and cooked through, about 8 to 10 minutes.
Transfer cooked meatballs to a plate lined with paper towels to drain excess oil.
Serve warm with a side of chilled tzatziki sauce.
