Sausage, Peppers, and Onions with Melty Caprese

I love sausage and peppers and I love a caprese salad, so I thought: Why not combine the two, but melt the cheese? I gave myself a real good pat on the back for this one, thank you. Everything is prepared and cooked in the same pan, making this a breeze to assemble and leaving you with only some bread to toast and a bright and bitter salad to toss to round out this one-stop shop.
