Step by step

1. Put the quinoa and cold water in a small saucepan. Bring to the boil, then cover with a lid, reduce heat and simmer for 10 minutes. Remove from heat, stir and leave to stand for 5 minutes with the lid on. All the water will be absorbed by the quinoa.

2. Scald the fresh peas in boiling water for 2 minutes, drain and rinse under very cold running water. Put them in the KitchenAid Artisan Food Processor bowl with half the quinoa, the rice flour, oil, mustard sauce, 1 tablespoon of lemon juice and capers. Put the Food Processor on speed 1 until you obtain a coarse creamy mixture, then switch it off and pour the mixture into another bowl, scraping the sides of the mixer bowl clean. Add the rest of the quinoa and combine.

3. Switch on the grill of the Artisan Twelix Oven, setting it to low.

4. Prepare 2 thick hamburger patties with the quinoa and pea mixture, shaping them with your hands slightly wet. Cook for 3 minutes on either side in a non-stick frying pan with a few drops of olive oil. Turn them just once with a flat spatula (so that they don’t break).

5. Remove the skin and pit from the avocado, cut the flesh into slices and sprinkle with lemon juice to prevent them from turning black. Cut the tomatoes into slices and wash and dry the arugula and parsley with kitchen paper. Assemble the hamburgers by stacking the ingredients one on top of the other, as you like, adding salt and pepper to taste.

6. Top with the other half of the bun, and serve immediately.
