Start by creating your marinade. In a bowl, combine the soy sauce, water or beef broth, minced garlic, rice vinegar, honey, paprika, oregano, and optional ginger. Whisk it thoroughly until the honey dissolves, and the ingredients blend smoothly.

Place your cubed top sirloin in a resealable plastic bag or a shallow dish. Pour the marinade over the beef, ensuring every piece is well-coated. Seal the bag or cover the dish, and refrigerate for at least 20 minutes. This step enhances the flavor and tenderness of the meat.

Heat a large skillet or wok over medium-high heat. Add one tablespoon of vegetable oil and one tablespoon of sesame oil. This mixture will help sear the meat beautifully while keeping it from sticking to the surface.

Once the oil is hot, remove the steak from the marinade, reserving the marinade for later. Add the steak bites in a single layer. Avoid overcrowding the pan; you may need to do this in batches. Cook for about 3-4 minutes until the steak develops a nice sear. Use tongs to flip the pieces for even cooking.

After you’ve cooked the steak bites, pour the reserved marinade into the skillet. Bring it to a gentle boil while stirring. This will create a luscious glaze that coats the beef. If you wish for a thicker sauce, add the cornstarch mixed with a bit of cold water. Stir continuously until the sauce thickens.

Once the sauce reaches your desired consistency, remove the skillet from heat. Plate your honey garlic steak bites, and sprinkle them with sesame seeds and sliced green onions for garnish. Enjoy with your selected sides and watch your guests swoon over the flavors!
