Butternut, sweet potato & grain burgers

1. Simmer the squash and sweet potato in salted water for 8-10 minutes until tender, then drain and mash. Mix with the grains and rice, 2 tsp paprika, chopped parsley, lemon zest and 1 tsp flour; season. Shape into 4 burgers, dusting your hands with a little flour to help.

2. Heat the oil in a nonstick frying pan and cook the burgers over a medium heat for 5 minutes on each side, until dark golden. Meanwhile, heat the grill and toast the buns, cut-side up. Stir the garlic into the mayonnaise and toss the parsley leaves with the rainbow salad.

3. Put a handful of salad leaves on each bun bottom and sit a burger on top. Add a good dollop of garlic mayo and sprinkle with a little paprika, then add some red pepper slices and beetroot shreds from the salad. Put each on a plate, squeeze over the lemon juice and add the bun top. 

Cook’s tip
This burger mix also makes a good alternative to falafel in a warm salad. Shape into rounds and brown in oil. Tumble with the rainbow salad, a can of chickpeas, crushed garlic and a little lemon juice and olive oil.
