1/2 c finely chopped onion
1/2 c finely chopped mushroom
1/4 c finely chopped celery
2 garlic cloves, minced
2-1/2 tsp olive oil

1/4 c crumbled gorgonzola cheese
4 boneless skinless chicken breast
1/4 tsp salt
1/4 tsp pepper
1 egg white
1/4 c ground walnuts
Saute onion, mushroom, celery and garlic in oil until tender.
Stir in spinach and cheese, remove from heat.
Cut lengthwise slits in thickest part of chicken, fill with mixture, sprinkle with salt and pepper.
Place egg white and walnuts in separate bowls, dip one side of chicken in egg white, then in walnuts.
Place in 11 X 17 baking dish coated with cooking spray and bake uncovered at 350 for 25-30 minutes.
