In a wok or large skillet over medium high heat, add the oil, shallots, garlic, ginger and bell peppers and sauté for 2-3 minutes.
Push the veggies off to the side and add the ground beef, breaking it up into small pieces as it cooks.
In a small bowl, stir together the brown sugar, fish sauce, soy sauce, oyster sauce, chili paste, cornstarch, beef broth, and water and add to the pan.
Simmer for 5-10 minutes.
Add the basil and stir. Serve over hot steamed rice, with chopped green onion on top.
