Classic beef and broccoli stir-fry gets a tropical makeover with sweet pineapple and the most AMAZING sauce ever! Ready to go in 20 minutes and you probably have all the ingredients!
In a large skillet over medium-high heat, brown beef, broccoli, onion, and garlic in olive oil until broccoli is nearly tender and beef is no longer pink. Reduce heat to medium.
In a small bowl, whisk soy sauce, pineapple juice, vinegar, sugar, and cornstarch until smooth. Pour over beef and add pineapple tidbits. Stir occasionally until sauce is thickened and bubbly. Season with salt and pepper to taste and serve stir-fry warm over hot rice. Enjoy!
