Sumac Onions - cooking recipe

Ingredients

2 large sweet onions
1 1/2 teaspoons ground sumac

Preparation

Peel and slice the onions as thinly as you possibly can (paper-thin would be great here, if you can manage it).
Toss the onions with the sumac (or the paprika, cayenne and lemon juice, if using).
Serve as a condiment on any Middle Eastern type sandwich (such as kebab).
