    Abstract: An outdoor grill (20) having interchangeable cooking accessories (60, 70, 80, 90, 100). As examples, the cooking accessories may include a hot dog cooker (70), a steamer, a food preparation assembly (60), a side burner, a griddle (80), a deep fryer (90), a rotisserie (100), or other cooking accessories. At least some of the cooking accessories may be sold separately from the grill (20), permitting a user to upgrade accessories when desired, or when cost constraints permit. A single grill frame and firebox (22) may be sold in the same store with different cooking accessories. Alternatively, the grill (20) may be sold in one store with a particular cooking accessory or accessories, and in another store with a different accessory. Some combinations may be sold only at particular stores, allowing a manufacturer to market specific grill combinations to a particular chain or store, and thus channel differentiation.
