- In a large skillet, melt the butter over a medium heat.
- Add the onions and season with salt, pepper and half of the 1 tsp thyme.
- Cook the onions until they are caramelized and have a jam like consistency, stir occasionally – Pour in 1/4 cup of broth if pan gets too dry,
- Add in the balsamic vinegar and remaining broth.
- Cook until the sauce thickens slightly.
- Stir in the garlic and cook for about 1 minute until fragrant.
- Remove from heat and allow to cool slightly.
- Cut chicken breasts in half, horizontally
- Cut the chicken breasts to create pockets.
- Chicken should be seasoned all over and inside the pockets as well, with salt, pepper, garlic powder and 1 tsp thyme.
- In each pocket, place half a slice of cheese
- Then spoon in 1 – 2 tbsp of the caramelized onions.
- Place chicken in baking dish
- Transfer the remaining caramelized onions from the skillet to baking dish.
- Bake for 25-30 minutes or until fully cooked.

Notes:
You can use shredded cheese instead of sliced cheese, in which case I would mix with the onions in the skillet and spoon in together
