Toss the squid and tomatoes in olive oil, salt, and pepper. Fill each tube with mozzarella, but leave about an inch at the end. Secure each end with a toothpick to hold in the cheese.
Heat a grill pan on medium-high heat. Add the squid and quickly sear on both sides. Be sure not to over cook the squid, only about 2 minutes per side.
Add the cherry tomatoes so that they char and slightly blister.
Finish with a pinch of salt and serve warm.
