A Slim Jim is a popular American, spicy, smoky, cured meat snack stick made by Conagra Brands, known for its distinctive savory flavor and convenient, portable "snap" format, originally created in the 1920s as a slimmer alternative to pepperoni for bar patrons. It's a jerky-like snack, but with a different recipe, often containing beef, chicken, soy protein, and flavorings, and comes in various sizes and flavors, marketed as a protein-packed snack.
