Parboil elbow macaroni about 5 minutes, until very al dente but cooked through. Rinse under cool water in a colander, drain thoroughly and set aside in a large bowl. Melt butter in a Cuisinart® 3¾-quart saucepan; stir in flour. Cook, stirring constantly for 3 minutes. Add milk; stir until it boils. Stir in Worcestershire sauce, dry mustard, salt and pepper. Turn off heat; stir in Cheddar and Gruyère until blended. Add to pasta and stir to combine. Lightly coat the interior of the ceramic pot of the Cuisinart® Slow Cooker with cooking spray. Add half the macaroni mixture. Spread the drained tomatoes in a layer; top with the mozzarella, then the remaining macaroni. Combine breadcrumbs and Parmesan; sprinkle over top. Cover and press the on/off button to turn the unit on. Set time to 5 hours and press Low; slow cooker will automatically switch to Warm when cooking time has elapsed.
