Ingredients:

2 medium sweet potatoes, peeled and chopped
1 cup brown rice
Half a red onion, chopped
Half a red pepper, chopped
Tin of kidney beans, rinsed and drained
4/5 leaves wild garlic, or a crushed clove of garlic
1 teaspoon vegetable stock
1 teaspoon dried mixed herbs
1 tablespoon chopped fresh thyme
2 tablespoons flour
Cracked black pepper to season

Method

1. Preheat the oven to 200 Celcius, grease a baking tray with oil or butter then sprinkle on some flour to prevent the burgers sticking.
2. Put the rice in a pan of  water, bring to the boil and cook for 10 minutes, before adding the sweet potato. Cook for a further 10 minutes.
3. Add the onion to the pan and cook for a further few minutes to soften.
4. Drain the pan, then add all of the other ingredients, stir well
5. Use a hand held blender to lightly pulse the mixture, so that it is smooth enough to form burger shapes but still has some texture.
6. Flour your hands then shape the mixture into balls then flatten onto the baking tray. Bake for 20-25 minutes.
