Crock Pot Pot Roast

3-4 lb beef roast
1 packet ranch dressing mix
1 packet italian dressing mix
1 packet brown gravy mix
4 red potatoes, cut into quarters
4 large carrots, cut into 2 inch pieces
1 large onion, cut into quarters
1 cup water

Place roast, veggies and water in crock pot. Sprinkle seasonings over the top. Cook on low for 8 hours. Sometimes I omit the veggies and do mashed potatoes and green beans on the side instead. YUM!!
