Preheat oven to 375° F.
Mix flour, yeast, salt and sugar in food processor.
Blend melted butter with 1 cup warm water.
Add mixture gradually to the dry ingredients through the feed tube of a food processor until the dough forms a ball.
Place in a greased bowl, coating the dough.
Cover with plastic wrap topped with a hot. damp towel.
Let rise until double in bulk (1-2 hours).
Divide the dough into tennis ball size pieces.
Spread out the seeds on a smooth surface and roll each tennis ball sized piece as thinly as possible, about 12 inches. Shape can be irregular.
Bake on an ungreased cookie sheet until each piece is a light golden brown with darker highlights - about 13 minutes.
