Preheat the oven to 375 degrees F (190 degrees C). Grease a 9x13-inch pan.

Cut the rolls in half. Set the bottom halves into the bottom of the prepared pan and spread a layer of marinara sauce on each. Place a layer of mozzarella cheese over the marinara and add a layer of tomatoes over the cheese. Spread basil over the tomatoes and add the top halves of the rolls.

Combine melted butter, Parmesan cheese, garlic, and Italian seasoning in a bowl; stir to combine. Brush over the tops of the sliders.

Bake in the preheated oven until the insides are gooey and the tops are golden brown, 10 to 15 minutes.
