We keep these steak tacos super simple by just broiling flank or skirt steak. However, when eaten with a spoonful of guacamole, they have all the flavors you'd expect of your favorite Tex-Mex dish. Our quick broccolini will also feel like a restaurant dish that's so easy to prepare at home
Position top rack ~6 inches (15 cm) from broiler and preheat broiler
Place steak on a foil lined sheet pan and broil on each side for ~3 minutes for medium-rare, ~4 minutes for medium, and ~5 minutes for well-done. When steak is done, take out of oven and let rest. Turn oven off, wrap tortillas in foil, and throw into the oven to warm up
Place broccolini in a microwave safe container. Add water and sprinkle with some salt. Cover with a lid or wet paper towel and microwave until tender, 1 1/2 to 2 1/2 minutes depending on thickness. (This extra step makes the broccolini saute much faster.)
Chop avocados and then make guacamole by combining with shallots, half of garlic, chopped cilantro, and lime juice with salt and pepper. Season to taste with salt and hot sauce
Heat a saute pan over medium-high heat. Add cooking oil and then other half of garlic to the heated oil. Add in microwaved broccolini and sprinkle with salt. Toss for another minute and then finish with squeeze of lemon juice. Season to taste with salt
If making tomorrow night's dinner, save half of steak and only slice tonight's portion. Otherwise, slice it all
Serve tacos with remaining lime wedges and let everyone assemble their own. Feel free to even chop up broccolini and use as taco fillings too!
