"Create a dairy-free, gluten-free, corn-free version of rigatoni with sausage and peas inspired by the linked Taste of Home recipe. Keep it beginner-friendly, quick/easy (15-30 min if possible), for a household of 3, using minimal processing and low-inflammation-friendly ingredients. Use imperial units only. Avoid gluten, dairy, nuts, shellfish, soy, sesame, and corn. Include ingredient substitutions for pasta, sausage, broth/seasonings if needed, and keep the flavor profile similar to a comforting sausage-and-pea pasta."
