- 1 cup Lentils (Can be replaced with cooked quinoa or chickpeas)
- 1 medium Onion (Opt for shallots for a milder taste)

Instructions
- Step 1: Preheat the oven to 400°F (200°C).

Tips & Variations
- For a richer topping, blend the mashed sweet potatoes with a bit of vegan butter before spreading.
- Mix in some sautéed mushrooms or spinach into the lentil base for extra flavor and nutrients.

Instructions
- Preparation: Preheat your oven to 400°F (200°C) to get it ready for baking the final pie.

- Dried herbs can be used if fresh thyme and rosemary are unavailable.
- Plant-based milk (like almond or oat milk) added to mashed sweet potatoes enhances creaminess and keeps the dish vegan.
- Ensure vegetable broth is gluten-free if dietary restrictions require it.
- Letting the dish cool slightly after baking helps it set and improves serving.
