This recipe always amazes me. It all comes together with such vibrant flavors. Serve it with saffron rice and some peas and you have a great meal. I even cook the rice on the grill. It adds a little smokey flavor to the rice which I like. The is adapted from the Fog City Diner. —thirschfeld
Cut the tops off the dried peppers and shake out the seeds into the trash can. Place the peppers into a bowl and cover them with hot water. Let them soak for two hours, making sure they stay submerged. Remove the peppers from the water and place them into the bowl of a food processor. Add a 1/2 cup of the soaking liquid to the bowl. Process until you have a pepper paste. Pass the paste through a strainer set over a bowl. You are removing the skins and seeds. Don't skip this step or you will be severely disappointed.
Combine 3 tablespoons of the paste with the remaining marinade ingredients and mix to combine. Season it with a healthy pinch of salt and a grind or two of pepper.
The marinade can easily be made a day or two in advance and stored in a jar in the fridge. The leftover pepper paste is great for enchiladas, black bean soup or chili. Store the paste in a jar in the the fridge. It holds for a long time.
Pound out the chicken breasts so they are of an even thickness, then place the chicken into a casserole. Use half the marinade and coat the pieces of chicken. Let them marinate for two hours. Be sure to flip them after an hour.
While the chicken marinates, make the lime pickled onions by tossing the red onion rings with the lime juice. Let them sit for at least 20 minutes.
Remove the chicken from the marinade. Place the marinade into a small sauce pan and heat it over low heat. Heat the marinade to a brisk simmer.
Fire up the grill to medium-high heat. Grill the chicken breast. Cook them till done. Serve on rice, spoon the hot marinade over the chicken, top with sour cream, then pickled onions, and garnish with cilantro.
