Ingredients

Scale

For the Meatballs

1½ pounds halal-certified ground beef or ground chicken
1 medium zucchini, grated
½ teaspoon salt
1 cup Italian-style breadcrumbs
1 large egg
½ cup grated Parmesan cheese
3 cloves garlic, minced
2 tablespoons chopped fresh parsley
1 teaspoon Italian seasoning
½ teaspoon onion powder
½ teaspoon black pepper
2 tablespoons olive oil (for browning)

For the Sauce

3 cups marinara sauce
1 teaspoon Italian seasoning
½ teaspoon garlic powder
¼ teaspoon crushed red pepper flakes (optional)

For the Subs

6 sub rolls
2 cups shredded mozzarella cheese
2 tablespoons butter, melted
1 teaspoon garlic powder
1 teaspoon dried parsley

Instructions

Prepare the Zucchini: Wash and grate the zucchini using the large holes of a box grater. Place the grated zucchini in a clean kitchen towel and gently squeeze out as much moisture as possible to help the meatballs hold their shape.
Make the Meatball Mixture: In a large mixing bowl, combine the ground beef or chicken, grated zucchini, breadcrumbs, egg, Parmesan cheese, minced garlic, chopped fresh parsley, Italian seasoning, onion powder, salt, and black pepper. Mix gently with your hands or a spoon until just combined, avoiding overmixing to keep the meatballs tender.
Shape the Meatballs: Roll the mixture into approximately 18 evenly sized meatballs, about 1½ inches in diameter. Place them on a plate or baking sheet as you work.
Brown the Meatballs: Heat the olive oil in a large skillet over medium heat. Cook the meatballs in batches, turning occasionally, until browned on all sides, about 6–8 minutes. They do not need to be fully cooked at this stage. Transfer the browned meatballs to a plate.
Simmer in the Sauce: Pour the marinara sauce into the same skillet. Stir in the Italian seasoning, garlic powder, and crushed red pepper flakes if using. Return the meatballs to the skillet, spoon sauce over them, cover, and simmer for 15–20 minutes until the meatballs are cooked through and reach an internal temperature of 165°F (74°C) for chicken or 160°F (71°C) for beef.
Prepare the Rolls: Preheat the oven to 375°F (190°C). Slice the sub rolls lengthwise without cutting all the way through. Mix the melted butter with garlic powder and dried parsley, then brush the mixture over the cut sides of the rolls. Toast the rolls in the oven for 5–7 minutes until lightly crisp.
Assemble the Subs: Place three meatballs inside each toasted roll. Spoon extra marinara sauce over the meatballs and top generously with shredded mozzarella cheese.
Melt the Cheese: Return the assembled subs to the oven for 3–5 minutes, or until the cheese is melted and bubbly. For extra browning, broil for 1–2 minutes while watching carefully to avoid burning.
Garnish and Serve: Optionally sprinkle with chopped parsley and extra grated Parmesan cheese. Serve immediately while hot with melted cheese.

Notes

Squeeze as much moisture as possible from the zucchini to keep the meatballs firm.
Mix the meatball ingredients gently to maintain a tender texture.
Brown the meatballs before simmering to develop extra flavor.
Use freshly grated mozzarella for the best melt and texture.
Toast the rolls before assembling to prevent sogginess.
If the sauce thickens too much during simmering, stir in a splash of water or broth.
Leftover meatballs can be served over pasta, rice, or mashed potatoes.
For a gluten-free version, use gluten-free breadcrumbs and sub rolls.
Meatballs can be baked instead of fried: bake at 400°F (204°C) for 18–20 minutes, then simmer in sauce.
To keep subs from getting soggy, avoid adding excessive sauce directly to the bread.
Meatballs can be prepared a day ahead and refrigerated before cooking.
