Instructions

Greek Meatballs:

  • In a large bowl, combine the first 10 ingredients (from lamb to salt) and using your hands, mix well to combine.
  • Form mixture into about 12 round meatballs and place on a baking sheet.
  • Add 1 Tbsp olive oil to a large skillet over medium heat.
  • Add half the meatballs to the skillet and cook, turning occasionally, until browned on all sides, about 6-9 minutes. Remove to a paper towel-lined plate.
  • Repeat with second batch, adding more olive oil to pan if needed.

Spicy Tzatziki:

  • Using a box grater held over a kitchen towel, grate ½ the cucumber. With the towel held over the sink or a bowl, squeeze as much excess water as possible from the cucumber.
  • Finely chop the remaining half of the cucumber.
  • In a medium-sized bowl, combine Greek yogurt, lemon juice, jalapeño, minced garlic, chili powder, dill, and mint.
  • Fold in grated cucumber and chopped cucumber and let tzatziki chill in fridge for at least an hour before serving.

Greek Salsa:

  • In a medium-sized bowl, combine all ingredients and mix well.

Assembly:

  • Spread spicy tzatziki on sub rolls and place three meatballs on top.
  • Spoon Greek salsa over the meatballs and add more tzatziki on top, if desired.
