Heat about 1 Tbsp. of oil in a pan add onions and allow to sauté of a couple of minutes.
Add in ground beef, salt, pepper and garlic. Cook until beef is browned.
Drain excess fat. Add ketchup, mustard, brown sugar, Worcestershire, and sriracha. Cook 1-2 more minutes, then remove from heat.
Lay egg roll wrappers out and place 2 heaping tablespoons of the sloppy joe mixture on each one. Top with a cheese.
Dip a finger or small brush in water and moisten the top edges of the egg roll wrapper. Roll up from the bottom, fold in the sides, and the continue rolling until the top edges seal the roll closed.
Heat oil to 350 degrees. Using tongs, carefully drop a sloppy joe roll into the oil and fry for 1-2 minutes on each side until golden brown.
