In large mixing bowl combine warm water, sugar and yeast. Let stand about 5 minutes till very bubbly. With wire whisk add the rest with only 1 cup of the flour, beating to smooth dough. Beat in rest of flour until batter is thick and sticky but smooth, all flour being dissolved.
Divide dough between 5 ovenproof, Pam-sprayed, cornmeal dusted (let excess shake out) soup bowls (each 5 inches in diameter). Cover each one in a square of Saran wrap sprayed in a bit of Pam and that side down. Let rise almost an hour or till above rim of bowls or cans. Discard Saran pieces.
Bake on center rack of 375° F oven about 20 minutes or till golden brown. Let cool in containers on rack, spraying tops each in a bit of Pam while they cool to keep crusts soft.
To use for sandwiches - slice in half horizontally and grill on lightly buttered hot griddle as you would for grilled cheese sandwich or broiler toast till golden.
Then fill with lettuce and assorted lunchmeats and cheese or sandwich fillings.Makes 4 Source:
