Preheat your Oven to 400°F. Line a large Baking Sheet with Parchment Paper and lightly coat with Cooking Spray.

In a large Mixing Bowl, combine the 1 ¼ lb ground turkey 93% lean, ⅓ cup plain breadcrumbs use gluten-free breadcrumbs if needed, ¼ cup Parmesan cheese finely grated, 1 large egg, 3 cloves garlic minced minced, 2 tbsp fresh flat-leaf parsley finely chopped, 1 tsp dried Italian seasoning, 1 tsp kosher salt, ¼ tsp black pepper freshly ground, and 2 tbsp whole milk keeps meatballs moist. Mix gently with your hands or a fork just until everything is evenly combined — do not overwork the meat or the meatballs will be tough.

Using a tablespoon or a small cookie scoop, portion the 1 ¼ lb ground turkey 93% lean into balls about 1½ inches in diameter (roughly 1 ½ tbsp each). Roll each one gently between your palms and place on the prepared Baking Sheet, spacing them about 1 inch apart. You should get approximately 20–22 meatballs.

Use sliced bread at room temperature for even results. For rolls or baguette-style loaves, slice in half lengthwise to expose more surface to the heat. For crispier French-style bread, lightly mist or rub the outside with water before loading it in. If adding cheese or toppings, have them ready to go. Position the rack in the center of the Toaster Oven before you start.

Preheat on the toast or bake setting. Toaster ovens run hotter and faster than full-size ovens, so ignore Oven timing. Standard sliced bread on a medium setting is done in 2 to 4 minutes depending on your model and slice thickness. Place bread directly on the rack or on a small Aluminum Foil-lined pan with space between pieces for even heat circulation. For rolls or French-style bread misted with water, set the temperature to 350°F to 375°F. The surface moisture creates a light steam effect that encourages a crisp exterior. Watch through the oven window rather than relying on a timer alone. Look for a deep golden-tan color. For a cheese melt, let the bread warm and lightly color first, then add cheese and continue until fully melted and bubbling. Use the broil function for even coverage. If the top browns too fast, loosely drape a small piece of foil over it to slow browning without stopping the cook.
