"Create a dairy-free, corn-free, gluten-free version of Beef Paprikash with Fire-Roasted Tomatoes inspired by the linked recipe. Keep it beginner-friendly, quick/easy if possible, and use minimal processing. Make it suitable for a household of 3, with imperial units only. Avoid all dairy, gluten, and corn ingredients. Use a creamy substitute that is dairy-free and gluten-free (for example, coconut cream or another safe option) and ensure any thickener is gluten-free and corn-free. Include ingredient substitutions and clear step-by-step instructions."
