Heat a skillet over medium-high heat.

Add ground beef to the skillet and break apart with a spatula.

Once beef begins to brown, add sliced onions and bell peppers.

Cook until beef is browned and vegetables are softened, about 5-7 minutes.

Drain excess grease from the pan.

Reduce heat and mix in Worcestershire sauce and cream cheese.

Season with salt and pepper to taste.

Use the mixture to fill and roll, then bake if necessary.
