Place steak in a shallow bowl and season liberally with salt, freshly cracked black pepper, and crushed red pepper. Squeeze 1 lime over the meat; turn to coat. Set aside for 30 minutes.
Make radish pickle:
Combine radishes, slices of fresh jalapeño, white vinegar, and 3 tablespoons water in a small bowl and stir to coat. Season with lots of salt. If liquid does not cover radishes, mix together equal parts white vinegar and water and add to bowl until radishes are covered. Set aside for 30 minutes.
Make pineapple salsa:
Combine diced pineapple or mango, juice of 1/2 lime, 1 tablespoon chopped cilantro, and 1 tablespoon red onion in a medium bowl. Stir to combine. Set aside.
Make cilantro-lime cauliflower rice:
Heat cauliflower rice until cooked through in the microwave or on the stovetop. If heating on a stovetop, add cauliflower rice and a little water to a medium saucepan and cover. Cook over medium heat until steamed. When cooked, stir together rice, 2-4 tablespoons chopped cilantro, and the juice of 1/2 a lime. Season with plenty of salt. Set aside.
When steak has marinated 30 minutes, heat a large cast-iron skillet over medium-high heat until very, very hot. Add 2 teaspoons avocado oil and let heat briefly. Carefully remove steak from bowl and place in pan. Sear, without moving, 4 minutes on the first side. Flip and cook another 2-3 minutes on the second side. Transfer to a cutting board and let rest 5 minutes.
Combine avocado, juice of 1/2 lime, 1/3 cup chopped cilantro, and 4 tablespoons chopped red onions in a large bowl. Sprinkle generously with salt. Mash to desired consistency and add more lime juice or salt to taste.
Slice steak against the grain. Spoon cauliflower rice into serving bowls and top with steak. Spoon pineapple salsa around steak and top with half the guacamole per bowl. Garnish with the radish pickles, and additional chopped cilantro and red onion.
To make this recipe easier, prep the cilantro, red onion, and limes from the first ingredients section. Then follow the directions to divide each ingredient by element (pineapple salsa, guacamole, etc.).
