Preheat the oven to 400°F. Split and butter the inside of the brioche buns. Place on a baking sheet lined with parchment paper or aluminum foil, buttered sides up. Set aside.
Warm a large (10-inch) skillet over medium-high heat. Add ground beef and salt. Cook until meat is browned and cooked through, using a spatula to break up the ground beef as it cooks.It isn't necessary to drain the beef drippings unless the beef is drowning in them.
Sprinkle Mexican seasoning over the beef and stir to combine.
Add tomato sauce, diced green chiles, and water. Stir to combine and continue cooking until the sauce thickens up, about 5 minutes.
Toast the hamburger buns in preheated oven for 6-10 minutes, or until they are lightly golden brown.Remove pan from oven and switch setting to broiler.
Sprinkle a tablespoon or so of cheese onto the insides of each of the top and bottom buns and place under the broiler for 1-2 minutes until just melted. **Don’t walk away from the oven - they can go from melted to burned in a blink.
Spoon a heaping portion of spicy sloppy joe on the bottom cheesy buns. Top with a small handful of Fritos and cilantro leaves, if desired. Cover with top cheesy bun. Serve and enjoy!
