Start by marinating the beef. In a bowl, combine the beef cubes with salt, pepper, and the juice of half the lime. Let it sit for about 20 minutes to absorb those flavors.
While the beef is marinating, rinse the rice under cold water until the water runs clear. Cook the rice according to package instructions, usually about 15-20 minutes in boiling salted water until fluffy.
In a large skillet over medium-high heat, add a drizzle of oil. Once hot, toss in the diced onion and sauté until translucent, about 3-5 minutes. Add the minced garlic and cook for an additional minute until fragrant.
Next, add the marinated beef to the skillet. Sear the beef on all sides until browned, around 5-7 minutes. This step is crucial for locking in those robust flavors.
Once the beef is browned, toss in the diced bell peppers and pineapple. The sweetness of the pineapple will beautifully balance the savory beef. Cook everything together for about 5-7 minutes, stirring occasionally until the peppers are tender and the beef is cooked to your liking.
Stir in the cooked black beans, and let them warm through for about 2-3 minutes. This will add a hearty texture and depth to the dish.
Now, it’s time to build your bowl. Fluff the cooked rice with a fork and divide it among your serving bowls. Spoon the beef and black bean mixture generously over the rice.
Finish with slices of creamy avocado on top, and a sprinkle of salt and freshly cracked pepper. Drizzle the remaining lime juice over everything for a zesty finish that brightens the dish.
