In a large skillet, sauté the cherry tomatoes with the onion and garlic for 10 minutes or until caramelized.
Add 1 tbsp of red wine vinegar and 1/4 cup water, and cook for another 5 minutes.
Place the cooked tomatoes and all of the stew ingredients (except for the peas and chives) in a slow cooker or Crock Pot. Set the slow cooker on the high setting and cook for 5 hours. Shred the chicken with a fork.
Once cooked, turn off the slow cooker and add the peas. Let the heat cook them for 5 minutes.
Serve the stew, topped with fresh chives.
