Serve this easy slow cooker chicken and shrimp with cooked fettuccine, linguine, or spaghetti. Boneless chicken thighs and chicken breasts are cooked in a simple tomato sauce and then the shrimp is added just before the dish is done. Feel free to use all chicken thighs or chicken breasts in the recipe if you prefer. Chicken and shrimp go surprisingly well together. Another possibility is 20-minute garlic chicken and shrimp. Or try our skillet chicken and shrimp with red sauce. Add garlic bread and a simple tossed salad for a satisfying meal.
