Step 1

Heat the vegetable oil (1 tablespoon) in a large skillet. Add the white and light green parts of the green onions, as well as the diced red bell pepper. Sauté until softened and starting to brown.

Step 2

Add the ground beef (1 pound.) to the skillet and cook/brown completely, breaking it apart with a wooden spoon as you go.

Step 3

Add the Korean BBQ sauce (1/2 cup) to the skillet. Stir together and bring to a simmer on low, simmering for 5 minutes or so uncovered until sauce has thickened. Stir in the dark green onions parts.

Step 4

Divide the beef mixture into the hamburger buns (4), garnish with more dark green onion parts if you have them, and sprinkle with sesame seeds if using. Serve.
