Preheat an oven to 375 degrees. Chop up THAWED broccoli and HALF of the pepperjack cheese into small pieces. Stir these ingredients together in a mixing bowl with the first amounts of olive oil, salt, and pepper; and stir in the garlic.
Step 2
Prepare 2 large chicken breasts by butterflying them nearly all the way through to create 2 deep pockets. Stuff half your broccoli mixture into both chicken breasts and secure them shut with toothpicks.
Step 3
Line a sheet tray with aluminum foil or parchment paper. Arrange the remaining broccoli filling into 2 portions on the sheet tray. Place a stuffed chicken breast on top of each broccoli portion. Sprinkle the remaining seasonings and olive oil over the top of the chicken breasts.
Step 4
Bake the chicken for 25 minutes. Then, lay the last slices of pepperjack cheese over the top of the chicken breasts and bake for an additional 7 minutes.
