Canned chili is a great way to save time when making chili dogs, but it's usually not that good on its own. To jazz it up, consider adding a little bit of diced pineapple.
Adding diced pineapple provides a hint of sweetness to the salty and savory flavors of the canned chili. For something less bold, add chopped sweet onion.
You can add crunch and a little spice by incorporating some fresh jalapeños. To enhance the chili dog further, add fresh herbs like cilantro, and dried spices like garlic powder.
