salt & black pepper, to taste
1 teaspoon garlic powder
1 tomato, diced
1 cup spinach, chopped
4 Tablespoons onion, roughly chopped
4 Tablespoons olive oil
4 Tablespoons balsamic vinegar
4 slices mozzarella cheese, cut into cubes
Preheat grill to medium heat.
Place cod on a piece of aluminum foil and season with salt, black pepper, and garlic powder. Add tomato, spinach and onion to cod. Season once more.

Create a packet with the foil and be sure to form a seal by crimping the edges together. Place the fish on the grill and cook until fish is flaky (7-9 minutes).
