Take a large skillet and let it preheat on medium-high.
Then, drizzle your avocado oil into the skillet and add your corn.
Allow corn to "grill" until you see a bit of charring happening, and turn the cobs over so that you get the same char happening on all sides.
Remove the corn cobs onto a plate and let it cool slightly while you prepare the steak.
Season steak with the garlic salt and sear it in the same pan used for the corn, but turn the heat up to high.
Cook to preferred level of doneness and then place meat onto a cutting board.
Let meat rest for a few minutes.
Use a knife to slice the corn off of the cobs.
Transfer the kernels of corn into a bowl and mix in other dry seasonings (chili powder and onion powder), along with chopped cilantro, and mayo.
Slice 1 lime and add the juice. Incorporate everything all together and let it rest in the bowl while slicing steak. (Remember to cut against the grain!)
Cook corn tortillas through in the same skillet used for the steak and corn (delicious flavors!) on medium-high heat.
Use "grilled" tortillas to assemble tacos by adding in sliced steak, corn mixture, and cheese.
Serve with additional lime wedges.
