Season the chicken with salt and pepper and sprinkle with flour, toss to coat the chicken in the flour.

Add sausage to pan and brown. When cooked through, remove from pan.
Add onions and bell pepper to pan, saute 5 minutes, or until starting to soften. Add the garlic, hot peppers and oregano and cook for 30 seconds, until the garlic is fragrant.
Add the chicken broth to the skillet and cook over high heat, scraping the bottom of that pan, until reduced by half, about 5 minutes.
Add the butter and lemon juice and stir until fully blended.
Return sausage and chicken to the pan, stir to coat everything in the sauce and cook for 2-3 more minutes before serving.
