In a large skillet over medium heat, brown the ground beef- about 5 minutes & breaking it up as it cooks.
Stir in the onions, and season the mixture with salt & pepper- to taste.
Continue cooking the mixture, stirring occasionally, until the onions have softened and begun to caramelize- about another 5-7 minutes.
Add the remaining ingredients to the skillet, stirring them in until evenly combined.
Bring the sauce to a simmer, the reduce the heat to maintain a slow simmer. Cook the mixture like that for 10 minutes, stirring frequently.
When the sloppy joe mix has thickened, remove the skillet from heat
Scoop the filling onto fluffy buns, or on slices of toast and serve as sandwiches.
