01 - Preheat your oven to 200°C (400°F). Line a baking sheet with parchment paper for easy cleanup.
02 - In a large mixing bowl, gently combine the ground meat, breadcrumbs, egg, chopped onion, minced garlic, milk, salt, pepper, and oregano. Mix until just incorporated, being careful not to overwork the mixture. Form the mixture into 16 small meatballs.
03 - Arrange the formed meatballs on the prepared baking sheet. Bake for 15 to 18 minutes, or until they are cooked through and lightly browned.
04 - While the meatballs are baking, prepare the glaze. In a small saucepan over medium heat, combine the cream soda, ketchup, soy sauce, brown sugar, and apple cider vinegar. Bring the mixture to a simmer.
05 - Stir the cornstarch slurry into the simmering glaze. Continue to cook, stirring constantly, until the glaze thickens to a glossy consistency, approximately 2 to 3 minutes.
06 - Once the meatballs are baked, gently toss them in the warm glaze until they are evenly coated.
07 - Divide the glazed meatballs among four snack boxes. Add the baby carrots, cucumber slices, cherry tomatoes, and optional cheese cubes to each box.
08 - Serve the snack boxes immediately, either warm or at room temperature. If not serving right away, refrigerate for later enjoyment.
