Adding Meat to Pasta Caprese
The problem you will find in using meat-based proteins for such a dish is that the whole point of Insalata Caprese (from which I presume this pasta is derived) is the light, fresh, bright flavours of tomatoes and basil and mozz. Meats will muddy that up.

You may wish to look into alternate protein sources. Serve the pasta with some nice crusty bread and a big bowl of garlicky pureed white beans.
