In a medium mixing bowl beat the eggs with the buttermilk. Remove the casing from the chorizo then add to the bowl along with the ground beef.
To the bowl add the shredded cheese, breadcrumbs, buttermilk, green onions, sun dried tomatoes, Worcestershire sauce and seasonings. Mix well and shape into bite size balls.
Fry in a large stove top pan in 1/2 inch of vegetable oil until brown and cooked through, around 5-8 minutes.
Place the meatballs on paper towels to drain. Keep warm until serving.
Serve with a side of cilantro pesto or a spicy tomato sauce.
Notes
Optional serving idea: Serve on warm tortillas or toasted hoagie rolls and make a Spanish meatball sub. Drizzle a spicy marinara sauce over the meatballs and sprinkle additional manchego cheese on top.
