Heat the olive oil in a large skillet over medium-high heat. Add the ground beef, chopped onions, and sliced bell peppers. Cook until the beef is perfectly browned and the veggies are tender-crisp. Carefully drain any excess grease.
In a small bowl, whisk together the soy sauce, beef broth, sesame oil, Swerve brown sweetener, oyster sauce, garlic, and ginger paste until smooth.
Add the rinsed and drained Palmini noodles directly into the skillet with the beef and veggie mixture.
Pour your freshly made savory sauce over the ingredients and toss everything together so it is beautifully coated.
