Juicy beef patties on a bed of fresh lettuce, topped with warm, hearty roasted vegetables, finished with a cheesy mustard sauce, and must-have burger fillings that everyone loves.
1. Set oven to 200ÂșC
Slice sweet potatoes and beetroots into rounds. Toss with 1 tbsp oil on a lined oven tray. Season with salt and pepper. Roast for 20-25 minutes, or until golden and tender.

2. Slice avocado and tomato. Grate carrot. Rinse and tear lettuce. Set aside.

3. Heat a large fry pan with 1 tbsp oil over medium-high heat. Cook patties for 4 minutes on each side, or until cooked through. Season with salt and pepper.

4. Heat a small saucepan over medium-low heat. Crumble in cheese, whisk in 1 tbsp mustard and 3 tbsp water until well combined.

5. Divide lettuce between plates. Stack with sweet potato and beetroot rounds. Top with patties, even amounts of cheese and fresh toppings.

Notes:
You can also crumble over the cheese if you prefer not to melt it. If you need another sauce instead, a burger relish or tomato sauce works well!

Slice rounds 1.5cm thick.

Reheat cheese if needed before serving.
