Step 1: Get that Ground Beef Ready: Grab your largest skillet and pop it over medium-high heat. Add your ground beef. Use a spoon to break it up into crumbles as it cooks. Keep going until it's all browned up – should take about 5-7 minutes. Once it's cooked, drain off any excess grease. Now, sprinkle that taco seasoning over the beef and pour in the water. Give it a good stir to make sure every bit of beef is coated. Let it simmer away for 5-7 minutes, or until most of the liquid is soaked up and the beef smells amazing and is well-seasoned. Slide the beef out of the skillet and set it aside for a moment.
Step 2: Whip up the Spicy Mayo: While your beef is simmering or cooling slightly, grab a small bowl. Add the mayonnaise, sriracha (start with 2 tablespoons, you can always add more later!), lime juice, and garlic powder. Whisk everything together until it's super smooth and creamy. Give it a little taste – need more heat? Add more sriracha! Set this aside too.
Step 3: Make the Cilantro Fried Rice: Wipe out that large skillet (or grab a wok if you have one!). Heat 1 tablespoon of the olive oil over medium-high heat. Toss in your finely diced onion and cook for just 2-3 minutes until they soften up a bit and become fragrant. Now, add your cooled cooked rice. Stir-fry the rice for about 3-5 minutes, breaking up any clumps with your spoon, until it's heated through and maybe starting to get a little toasted. Stir in that chopped fresh cilantro right at the end.
Step 4: Assemble Your Flavor Bombs: Lay one of your large flour tortillas flat on a clean surface. Sprinkle about 1/4 cup of your mixed shredded cheddar and Monterey Jack cheese directly onto the tortilla first. This acts as a sort of glue.
Step 5: Add the Beef: On one side of the cheese layer (think about where you'll start rolling), add about 1/4 of your seasoned ground beef.
Step 6: Pile on the Rice: Right next to the beef, add about 1/2 cup of your cilantro fried rice.
Step 7: Drizzle the Magic: Now, generously drizzle some of that incredible spicy mayo over the beef and rice. If you're using pickled jalapeños, scatter a few over the filling now too.
Step 8: Fold and Roll! Fold in the sides of the tortilla tightly over the filling. Then, starting from the bottom edge, tightly roll up the burrito towards the top. Repeat this process with your remaining tortillas and fillings.
Step 9: Time to Grill! Grab that large non-stick skillet or a griddle. Heat the remaining 1 tablespoon of olive oil over medium heat. You don't want it too high.
Step 10: Get Them Crispy: Carefully place your assembled burritos, seam-side down, onto the hot skillet. Cook for 3-4 minutes on that first side, until it's a beautiful golden brown and crispy. Then, use a spatula to carefully flip them over and cook for another 3-4 minutes on the other side, or until both sides are golden and crispy, and you can tell that cheese inside is wonderfully melted.
Step 11: Serve 'Em Hot! Remove the gorgeous, crispy burritos from the skillet. You can slice them in half diagonally if you like. Serve them immediately, maybe with a dollop of sour cream or a scoop of guacamole if you're feeling extra!
