Heat the olive oil in a skillet over medium-high heat and add the shrimp. Immediately add the red bell pepper into the skillet, and saute until the peppers have softened and the shrimp is cooked through.

In a bowl, combine the soy sauce, oyster sauce, brown sugar substitute, and minced garlic.

Mix the green onions, serrano pepper, and basil into the skillet, and saute for another 2-3 minutes.

Pour the chili garlic mixture over the mixture into the skillet and give it a good stir.

Finish off the cooking process by allowing it to saute for a minute or two longer and give it a final stir before serving.
