Preheat the oven to 425 degrees.
Make your tomato salad and throw in some sliced cucumbers too!
Pulse the garlic, parsley, cilantro, capers, and walnuts in a food processor until chopped very finely (but not creamy / not a paste). This is your flavor base!
Transfer half of the flavor base to a large bowl for the meatballs. Add all other meatball ingredients and mix thoroughly with your hands to combine. Roll into balls and bake for 10-12 minutes.
Add the other half of the flavor base to a smaller bowl; add lemon zest and lemon juice, olive oil, and salt and pepper to taste to make your sauce.
Serve meatballs over a swipe of tzatziki, with a hunk of rustic bread and a scoop of tomato salad. Drizzle, dip, and swish all of it through that punchy green sauce!
