- 1 (24 ounce) jar four-cheese pasta sauce (such as Classico®)
- 4 skinless, boneless chicken breast halves
- 2 cups fiesta-style four-cheese blend
- 8 slices Texas-style cheese toast
- Preheat oven to 400 degrees F (200 degrees C).

- Bake in preheated oven until no longer pink in the center and the juices run clear, 30 to 40 minutes. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C).
- Cover chicken breasts with a layer of cheese and continue baking uncovered until the cheese melts, about 10 minutes more.
- Arrange cheese toast onto a baking sheet.
- Bake cheese toast in preheated oven until cheese is melted and the toast is browned around th edges, about 10 minutes.
- Sandwich each chicken breast between two slices of the toast with the cheesy sides touching the chicken.
