time, and knead into a hard dough. Cover with a damp cloth and rest the dough for 15-20 minutes.
Take kidney beans in
another bowl, add corn kernels, tomatoes, tomato ketchup, lemon juice and salt and mix well.

two portions. Sprinkle some dry flour on worktop and roll each portion into thin discs. Cut them into 1 inch wide strips and then cut the strips into small triangles. Prick the triangles with a fork so that they do not puff up while baking.
