Preheat oven to 350 degrees.

Slice the Hawaiian rolls, or hollow out the centers, similar to a hot dog bun. Place on a parchment-lined baking sheet.

Place a cocktail sausage into each roll. (For kids under 4, slice sausages lengthwise first.)

Top each with a spoonful of warmed chili.

Sprinkle generously with shredded cheddar cheese.

Bake for about 10 minutes, or until the cheese is melted and the sausages are heated through.

Remove from the oven, sprinkle with green onions, and serve warm.
