Cut and prepare shrimp and beef into bite-sized pieces.
Slice vegetables (broccoli, bell peppers, onion, etc.) to a desirable size.
Add olive oil to a pan and stir-fry the beef over medium heat.
When the beef is partially cooked, add the shrimp and stir-fry together.
Once the shrimp is cooked, add the prepared vegetables and stir-fry.
Add basil leaves and season with salt and pepper.
When all ingredients are evenly cooked, turn off the heat and serve on a plate.
