Add 1 tablespoon of your olive oil in a pan, over moderate heat. Cook your beef for about 7-minutes or until browned, stirring often. Transfer your meat to a plate, then cover to keep warm.
In the same saucepan, heat your remaining oil, adding in the onion, and garlic. Stir-fry the garlic and onion for about 1-minute or until aromatic.
Add your eggplant, tomato puree, bell peppers, and soy sauce. Reduce the heat to a simmer. Cover your pan with the lid and cook for 15 minutes.
Add the beef to pan and cook for an additional 3-minutes. Season with salt and pepper, to taste.
Transfer to a serving platter.
Serve and Enjoy!
