One-Pot Shrimp and Chicken Couscous

Heat butter and olive oil in a large skillet over medium heat until butter is melted. Add broccoli, mushrooms, onion, garlic, Italian seasoning, and crushed red pepper; saute for 2 to 3 minutes. Add shrimp, chicken, and couscous; stir to coat.

Add chicken broth and lemon juice and bring to a boil. Cover, reduce heat to low, and simmer until chicken and shrimp are cooked through and couscous has absorbed all the liquid and is tender yet firm to the bite, about 10 minutes.
