Make the bacon jam: cook down the whole pack of bacon until fully cooked, then remove it, reserving the bacon fat.
Caramelize the diced onion in the bacon fat. Once golden, add the bacon back in along with a splash of beef broth, the Worcestershire sauce, brown sugar, and a pinch of salt. Cook down until jammy.
Cook the ground beef, seasoning with salt, pepper, and onion powder.
Assemble each eggroll: on an egg roll wrapper, layer American cheese, the beef, and a nice spoon of bacon jam. Roll up tightly, sealing the edge.
