Place the steak into the freezer for a couple of hours before cooking to firm up.
In a large bowl mix together 1 tbsp of oil, 1 tbsp of soy sauce, all of the seasonings, and the baking soda. Stir to combine, this is the marinade.
Use your sharpest knife to cut the steak into thin strips of about 1/4 inch in thickness and then across into a medium dice. You want this to be in small pieces.
Add the steak to the marinade and mix so each piece of beef is well coated. Massage the beef in your hands a bit to help tenderize it. Allowing it to marinate for 30 minutes to an hour is best but feel free to prep the other ingredients first, then cook the steak whenever you are done.
While the beef is marinating chop all of your vegetables. Cut the bell peppers into a medium dice, the onion into thin slices, and mince the garlic.
For the chipotle peppers in adobo sauce you will need 3 tbsp in total. The peppers are dried jalapeños so if you don't like spice, don't use too many. You can just take the adobo sauce and still get the flavor. For reference I used 2 peppers and the rest of the weight was in the sauce. Mince up the jalapeños.
Once the beef is ready to be cooked, heat a large skillet over medium heat. To achieve proper browning, it is best to cook this steak in batches to not overcrowd the pan. I have accounted for 1 tbsp of oil to assist in cooking this beef.
Add half of the steak and 0.5 tbsp of oil to the pan and spread it out across the surface to give it space between pieces. Because we cut this so thin it will cook quickly. Give it about 2 minutes over the heat, undisturbed, to develop color and then toss it around to the other side. Cook for an additional 2 minutes and remove it from the pan and store on a plate.
Add the remaining 0.5 tbsp of oil and beef and repeat the cooking process to finish off the beef. Remove from pan once finished.
There should be a bit of residual oil left in the pan so to cook the vegetables, add in 2 tsp (10g) with the onions and peppers over medium heat. Cook for about 2-3 minutes to allow them to soften a bit.
Next add in the corn and garlic and stir. Allow these to cook over the heat for another 1-2 minutes.
Create a well in the center of your pan and add in the rice, soy sauce, lime juice, and chipotle peppers in adobo sauce. Stir to combine and break up the rice.
Re add the steak stir. Taste test and adjust with salt to your liking.
