Hearty Oven Stew

This is an easy hands-off recipe that I got from my mom.  I served this stew with cornbread muffins that I'd made ahead and frozen for later use.

1 lb. stew meat

3 carrots, cut into 1" pieces
3 medium potatoes cut
2-3 stalks celery, slice
1 small onion, cut into large pieces
1 ½ t sugar
1 ½ t salt
⅛ t pepper
3 cans (10.5 oz-each) condensed tomato soup
3 c water

Combine raw meat and other ingredients in pot. Cover and bake at 300˚ for 3-4 hours.
