Easy Chicken with Onions, Mushrooms and Rosemary

6 chicken thighs, skinless and boneless
salt/pepper to season chicken
1T olive oil
1 red onion cut in wedges
Large box of sliced mushrooms
2 plum tomatoes, cut in large dice
fresh rosemary springs (I used 4)

Preheat oven to 350 F. Season thighs well on both sides with salt and pepper. 

Heat large oven proof frying pan, (I have a large cast iron skillet which is perfect for this) Add olive oil, and brown chicken very well on both sides.

Remove chicken from frying pan and put onions in and saute 2 minutes. Add mushrooms and saute 2 minutes more. 

Put chicken back in pan among the onions and mushrooms and scatter the tomatoes over all.  Put the whole springs of rosemary in pan. Roast 40-45 minutes, until chicken and veggies are done.

This was delish!!

This is how it looked when I put it in the oven! Yum-and as it bakes the house fills with rosemary!
