Here's a simple recipe to put together. It's what I made for dinner tonight when faced with only nothing planned and a package of chicken. I ended up using less than half a small jar of pesto, so it's good if you have some leftover in the fridge.
Jar of pesto
Chicken pieces of choice
1: Place chicken in shallow baking dish.
2: Spoon pesto over the chicken.
3: Bake at 350°F until done, this will depend on the cut and weight of the pieces, here's a chart or better yet use a probe thermometer to cook until the internal temperature is 165°F.
4: Share and enjoy.
