In a large mixing bowl, combine the beef with 1 teaspoon minced ginger and ½ of the garlic. Season with ½ teaspoon kosher salt. Roll the meatball mixture into 1-inch balls.
Heat the oil in a large skillet over medium-high heat. Add the meatballs and cook until well browned, 2-3 minutes per side. The meatballs should easily release from the pan when they're browned.
Push the meatballs to the edges of the pan and add the pepper and onion to the center. Cook for 3-4 minutes, until softened. Stir in the red curry paste and remaining garlic and ginger.
Pour in the coconut milk, fish sauce, and lime juice. Reduce the heat to medium and cook, stirring occasionally, for 10 minutes or until the sauce is reduced by about ⅓ and the meatballs are cooked through.
Stir in the basil and cilantro. Top with toasted coconut.
