Preheat your oven to 200°C (375°F). This is crucial as it ensures even cooking as your bake comes together. While the oven heats up, you can prep your ingredients.
In a large bowl, toss the capsicum and zucchini with a drizzle of olive oil, salt, and pepper. Ensure they are well coated, as this will enhance their flavor during roasting. Set them aside to allow the flavors to mingle.
Next, prepare the sauce. In a separate jug or bowl, mix the tomato paste with warm tap water to create a smooth sauce. This will be drizzled over your meatballs and vegetables later, adding a rich and savory element.
Now, to make the meatball mixture! In a bowl, combine the panko breadcrumbs and grate the onion over them. This will help absorb the moisture from the onion, creating a juicy meatball. Mix them together with your hands.
Add in the remaining meatball ingredients: lamb mince, egg, minced garlic, and spices (cumin, coriander, paprika, cinnamon, cayenne pepper, and salt). Get in there and mix everything well until combined.
Roll the mixture into about 16 meatballs, each approximately 1.5cm thick. Aim for consistency in size to ensure even cooking. You may find it helpful to wet your hands slightly to prevent sticking.
In a cast-iron pan or baking dish, start standing the meatballs upright between the zucchini rounds, gently tucking in the capsicum chunks. Arrange them artfully; this is your chance to create a beautiful dish!
Once all the meatballs and vegetables are arranged, pour the sauce evenly over everything. Drizzle a bit more olive oil on top for extra flavor and moisture.
Place the dish in your preheated oven and bake for about 35 minutes, or until the meatballs are beautifully browned and cooked through. You’ll know they’re done when the top looks golden and the aroma fills your kitchen.
When it’s time to serve, let the bake cool slightly. You can drizzle some thinned yogurt over the top for a creamy finish. Serve with flatbreads, rice, or couscous to soak up all that delicious sauce.
