THE GREEN MACHINE RECIPES

Steps:

• Slice the tomatoes (you can skin them if you want, but it's not necessary). Finely chop the onions. Layer both in a large bowl with the salt. Leave overnight.
• The next day, chop the sultanas using a large, sharp knife, then peel, core and chop the apples. Put the sugar and vinegar into a large pan and bring to the boil, stirring to dissolve the sugar. Add the sultanas and apples and simmer for 10 mins. Strain the tomatoes and onions in a colander (but don’t rinse), then tip into the pan and return to the boil.
• Simmer for about 1 hr, stirring occasionally until the mixture is thick and pulpy. Transfer to warmed jars (see tips, below) and cover with lids.

Steps:

• Heat half the oil in a frying pan and gently fry the onions for about 10 mins until pale and soft, then leave to cool a little.
• Finely chop the spinach in a food processor and tip into a bowl. Add the cooled onion, breadcrumbs, nutmeg, cheddar and Parmesan, and mash together. Add the beaten egg, a little at a time (you may not need all of it), until the mixture holds together. Divide into eight (see tip below) and shape into fat burgers.
• Put the flour in a shallow bowl, season well and dip the burgers into the flour to coat. Store in a plastic container between layers of baking parchment. Either chill until ready to cook, or freeze.
• Heat the remaining oil in the frying pan and fry for about 5 mins each side until browned all over. Serve in the crusty rolls, with a couple of slices of tomato, ketchup and sweet potato fries on the side, if you like.
