Instructions: Combine first 4 ingredients in a microwave-safe bowl. Stir in 1 cup water; cover with plastic wrap, folding back a corner to allow steam to escape. Microwave at HIGH 4 to 5 minutes or until thickened, stirring once. Stir in salsa.

Slice off top one-third of each bread loaf lengthwise; hollow out bottoms of loaves, leaving 1-inch-thick shells.

Place 1 cup lettuce in bottom of each shell. Layer each with half of roast beef, half of salsa mixture, and remaining roast beef. Sprinkle with tomato and cheese; spread with remaining salsa mixture, and sprinkle with remaining lettuce.

Cover with bread tops, and press down lightly. If desired, wrap in plastic wrap and chill.
