Drain and rinse the 28 oz of quartered artichoke.
Make the artichoke marinade. In a bowl mix together the lemon juice, 4 Tbs olive oil, and oregano. Add in the artichoke and gently, but thoroughly, mix it together. Set it aside for now.
Chop the onion, garlic and red pepper to get them ready, then set them aside for now.
Prep your chicken. Defrost it, trim the fat and cut any thick chicken breasts in half.
Cook your chicken. You can either put 1-2 Tbs of oil in a pan and pan sear the chicken. My preferred method is to grill the chicken using our indoor george foreman grill while the sauce cooks in a pan.
Put the remaining tablespoon of oil in a large pan. Add in the onion, red pepper and garlic and saute until softened.
Add the chicken broth and the heavy whipping cream. Stir occasionally and make sure to scrape the bottom of the pan to prevent burning. Bring the sauce to a low boil and allow it to simmer for 1 minute.
Lower the heat to low, then slowly add in the parmesan cheese while whisking constantly. Whisk until the cheese is melted and completely mixed in.
Add in the artichokes by gently stirring to mix them into the sauce.
Mix in the parsley, salt and pepper.
Submerge the chicken in the sauce and serve over rice.
