I found this recipe at Kraft Foods
1/3 cup shredded mozza cheese
1/4 cup pesto
1/4 cup dijon mustard (I used a little less than this)
4 sm chicken breast (or I used 5 chicken thighs)
Mix 1/4 cup of cheese with pesto and mustard.
Arrange chicken in single layer. Spread pesto mixture over chicken, sprinkle with remaining cheese.
Bake at 350 for 20-25 min or until chicken is cooked.
I served this with broccoli the other night...but I would suggest adding a second side like baby potatoes or risotto :) Both the men in my house ate it all up! Happy cooking!
