Make sun-dried tomato mayo by whisking 2 tablespoons Mezzetta Sun Ripened Dried Tomato Pesto into 1/4 cup mayonnaise; refrigerate until ready to use.
Preheat the oven to 350°F (175°C) and line or lightly oil a baking sheet.
In a large mixing bowl, combine 1 lb ground chicken, 1 lightly beaten egg, 2 tablespoons sun-dried tomato pesto, 1 tablespoon Mezzetta Savory Garlic Everything Spread, 2 tablespoons chopped fresh parsley, 1/2 cup Italian bread crumbs, and 1/2 cup grated Parmesan; mix gently until just combined.
Use a cookie scoop or tablespoon to portion the mixture into about 20–24 meatballs and place them on the prepared baking sheet.
Brush the tops of the meatballs lightly with 2 tablespoons olive oil and bake for 15 minutes.
Turn the oven to the broiler and broil the meatballs 2–5 minutes until lightly browned; remove and set aside.
Spread 1 tablespoon Mezzetta Savory Garlic Everything Spread on each split roll and top each with two slices provolone cheese.
Place the prepared rolls under the broiler 2–3 minutes until the cheese melts and the rolls are lightly toasted.
Divide 4–5 meatballs among the 4 rolls, placing them on top of the melted cheese so they stay in place.
Top each sandwich with sun-dried tomato mayo and additional chopped parsley if desired, then serve.
