# Instructions:

01 - First things first, let's get that steak ready! Pat your flank steak super dry with paper towels – this is critical for a good sear, trust me, I learned that the hard way. Slice it against the grain into thin strips, about ¼ to ½ inch thick. In a medium bowl, toss the steak with olive oil, lime juice, chili powder, cumin, smoked paprika, garlic powder, onion powder, salt, and pepper. Give it a good mix with your hands; you want every piece coated. Let it sit for at least 15 minutes, or even better, an hour in the fridge if you have time. This is where the magic starts for a flavorful result!
02 - While your steak is marinating, slice those beautiful bell peppers and onion into thin strips. Heat a large cast iron skillet (my secret weapon for a great sear!) or a heavy-bottomed pan over medium-high heat. Add a splash of olive oil. Once shimmering, toss in your peppers and onions. Sauté for about 5-7 minutes, stirring occasionally, until they’re tender-crisp and slightly charred. You want that little bit of caramelization, honestly. Don't overcook them; nobody wants mushy veggies in their fajita meal! Transfer them to a separate plate and set aside.
03 - Now for the star of the show! Reheat that same skillet over medium-high heat, adding another tiny drizzle of olive oil if needed. Once it's smoking a little, add the steak in a single layer. Don't overcrowd the pan, or it'll steam instead of sear – I've made that mistake too many times! Cook for 2-3 minutes per side for medium-rare, or longer if you prefer. You're looking for a beautiful, slightly crispy crust. The kitchen will smell amazing at this point, like a bustling taqueria!
04 - Once your steak is perfectly seared, remove it from the pan and let it rest on a cutting board for a few minutes. This lets the juices redistribute, making it super tender. If you want, you can quickly toss the cooked steak back into the pan with the sautéed peppers and onions for about a minute to warm everything through. This step isn't strictly necessary, but it helps marry the flavors even more. It's all about building that delicious fajita experience!
05 - If you’re using cauliflower rice, now’s the time to quickly steam or sauté it according to package directions. I usually just microwave a bag of frozen cauliflower rice for a few minutes. It's quick, easy, and the perfect low-carb canvas for all those amazing fajita flavors. Make sure it's hot and ready to absorb all those delicious juices from the steak and veggies. Honestly, don't skip this step if you want a complete and satisfying meal.
06 - Alright, the moment you've been waiting for! Divide your cauliflower rice (or whatever base you're using) among serving bowls. Top generously with the seared steak, bell peppers, and onions. Now for the fun part: garnishes! Pile on sliced avocado, a dollop of salsa, and a sprinkle of fresh cilantro. If you're feeling it, a spoonful of sour cream or Greek yogurt is fantastic. Take a deep breath and enjoy that incredible aroma. Your high-protein, low-carb Steak Fajita Bowl is ready!
