Cook the potatoes: bake or boil. If you bake them, pop them in an oven dish with a lid so that the skins don't go hard.
Grate the carrot into a large bowl. Mash in the potato, skin and all.
Next blitz the pepper, chickpeas, defrosted frozen peas and the date in the food processor. You want a chunky mixture rather than a smooth paste.
Stir the pepper mixture into the carrot and potatoes. Stir through the rest of the ingredients. Taste and adjust seasoning if necessary.
Blob onto a lined baking tray. Shape the delicate blobs into burger shapes.
Bake at 180C for about 30-40 minutes. Carefully turn half way through cooking. They are delicate but if they break simply press them back together.
They will firm up a bit as they cool. Serve hot or allow to cool completely on a wire rack then refrigerate or freeze.
Bake frozen burgers at 180C for about 20 minutes or until cooked through.
