After a long day at work, treat yourself to an easy—and nutritious—feast. Beef is a prime source of zinc, so this Pot Roast will help keep your immune system going strong.
Press dressing mix evenly onto all surfaces of beef pot roast. Place onions and garlic in 4-1/2 to 5-1/2-quart slow cooker; top with pot roast. Add bell peppers and broth. Cover and cook on HIGH 5 hours or LOW 8 hours. Add zucchini. Continue cooking, covered, 30 minutes or until pot roast is fork-tender.
Remove pot roast and vegetables. Strain cooking liquid; skim fat. Combine 2 cups cooking liquid and cornstarch mixture in medium saucepan. Bring to a boil, stirring constantly; cook and stir 1 minute or until thickened.
Carve pot roast into slices; season with salt and pepper, as desired. Serve with vegetables and gravy.
