Rub together the vegan spread and flour in a bowl.
Add the cheese, chilli powder, mustard and season with salt and pepper.
Work into a dough (if it's not sticking together, add a tiny bit of water, but I found the mustard bound it together well).
Roll out onto a lightly floured surface, trim the edges (or don't bother if you don't mind them looking 'rustic') and cut into strips about 1cm wide (I used a pizza cutter).
Line a baking tray with baking paper, lay the strips down, leaving a bit of a gap between them, glaze with soya milk and bake at 200C for about 10 minutes, until golden.
