Heat the oil in a deep 12-inch skillet over medium-high heat. Add the peppers and onion and cook until the vegetables are tender, stirring occasionally. Add the garlic and cook and stir for 30 seconds. Remove the vegetable mixture from the skillet.
Add the beef and cook until well browned, stirring often. Remove the beef from the skillet.
Stir the soup and lime juice in the skillet and heat to a boil. Return the vegetables and beef to the skillet and cook until the mixture is hot and bubbling.
