Yes. Any ketchup is fine in cases where sugar is listed lower than the third ingredient. The below recipe for homemade ketchup is fine for Bright Line Eating—you would treat it like a condiment, but limit it to 1 tbsp.

- 1 half of an apple diced (with or without skin)
- 1/3 cup water
- 1 tablespoon lemon juice
- ¼ teaspoon garlic powder
- ¼ teaspoon dried oregano
