"Create a beginner-friendly Puerto Rican rice and pigeon peas recipe (arroz con gandules) for a household of 3 using imperial units. Keep it quick and easy (15-30 minutes active time if possible), moderate budget, minimal processing, and suitable for an omnivore with no gluten, dairy, nuts, shellfish, or corn. Avoid those allergens entirely. Aim for a flavorful but not overly spicy version, using accessible ingredients and simple stovetop instructions. Include optional protein add-ins only if they fit the dish and remain allergen-safe."
