Saucy meatballs with melted cheese piled on hoagie rolls is total Italian-inspired comfort food. This updated version of a meal from 2017 uses leftover meatballs from earlier in the week, so it comes together quickly.
Make meatballs - (Skip if made ahead for Tuesday.) Heat oven to 375F / 191C degrees. Mix ground turkey with eggs, panko, salt, black pepper, and garlic powder. Brush or spray a sheet pan with some oil. Roll meatball mixture into small 1.5” / 4 cm wide meatballs and place onto sheet pan. Bake until just cooked through, 15 to 18 minutes. (Can be done up to 4 days ahead)
Turn on the oven’s broiler (low setting if possible) and place a rack about 8” / 20 cm beneath the heat source.
If the meatballs are too large to easily fit inside the hoagie rolls, slice in half before continuing.
Heat a large saucepan or Dutch oven over medium-high heat. Add cooking oil and then garlic, basil, and oregano (portion for subs) to heated oil. Cook just until fragrant, ~1 minute. Pour crushed tomatoes over top and bring to a simmer.
Remove sauce from heat and season with some salt and pepper. Stir meatballs into sauce.
Slice open hoagie rolls and lay out flat, cut-side up onto a sheet pan. Broil just until starting to turn golden brown, 2 to 3 minutes.
Divide meatballs and sauce between rolls. Top with mozzarella. Return to broiler and continue cooking until cheese is bubbly and melted.
Meanwhile, in a large mixing bowl, whisk together mayonnaise, vinegar, and oregano (portion for the salad). Add olive oil while whisking. Top with tomatoes, lettuce, and black olives. Toss to combine.
Serve meatball subs with salad on the side. Enjoy!
