Tuna Barbecue

Christopher wasn't home and the girls took one look at what was for dinner and fled. I'm on the fence with this one. The flavor was good but the texture was way too mushy for me. Maybe if you used a tuna steak and then flaked it prior to serving. Not sure if this recipe will ever make it to the table again.
Ingredients
12 oz can tuna, drained
2 cups tomato juice
1 medium green pepper, finely chopped
2 tablespoons onion flakes
2 tablespoons Worcestershire sauce
3 tablespoons vinegar
2 tablespoons sugar
1 tablespoons prepared mustard
1 rib celery, chopped
dash chili powder
1/2 teaspoon cinnamon
dash of hot sauce, optional
Directions
Combine all ingredients in slow cooker. Cover. Cook on low 8-10 hours or high 4-5 hours. If mixture becomes too dry while cooking add 1/2 cup tomato juice. Serve on buns.
