Heat oven to 350°F. For spread, soften tomatoes according to package directions; coarsely chop. In small bowl, combine softened tomatoes, mayonnaise, garlic and hot pepper sauce; mix well. Cover and chill. For meatloaf, combine all ingredients in large bowl; mix lightly but thoroughly. Press meat mixture evenly into 9 x 5-inch metal loaf pan. Bake 1 hour to 1 hour 15 minutes or until meatloaf is to medium doneness and center is no longer pink (160°F for beef; 170°F for turkey). Drain off any juices. Let meatloaf stand 5 minutes before cutting. To serve, cut focaccia into 8 rectangles; cut each rectangle in half horizontally. Spread 1 tablespoon spread on inside surfaces of each focaccia piece. Cut meatloaf into 8 slices; place on half the focaccia rectangles. Top with cheese and lettuce; cover with remaining pieces of focaccia. Serve warm.
