1Prepare the marinade by whisking together oil, soy sauce, garlic powder, onion powder, chili powder, paprika, black pepper, salt, and baking soda in a bowl.
2Cut the steak into thin 1/4 inch strips, then rotate and cut across to create small pieces.
3Add the steak to the marinade and mix thoroughly by hand, squeezing the meat to incorporate the ingredients.
4Chop the bell peppers into medium-sized dice.
5Cut the onion into thin strips.
6Mince the garlic.
7Mince the chipotle peppers in adobo sauce.
8Heat a large skillet over medium heat with oil and cook the steak in batches until browned.
9Transfer the finished steak to a plate to rest.
10In the same skillet, add extra oil and sauté the onions and peppers until softened.
11Add the frozen corn and minced garlic to the skillet and sauté for another minute or two.
12Create a well in the vegetables, add the cooked rice, and stir in soy sauce, lime juice, and the chipotle/adobo mixture.
13Mix the rice thoroughly with the vegetables, then add the cooked steak and any accumulated juices back into the pan.
14Portion into five meal prep containers and garnish with lime wedges and cilantro if desired.
Freeze the steak for a couple of hours before cutting to make it easier to slice into uniform pieces.
Squeezing and beating the meat with the marinade helps tenderize the top round steak.
To reduce heat from the chipotle peppers, press against them in the can with a spoon to squeeze out the sauce and use that instead of the pepper flesh.
Cook the beef in batches to avoid overcrowding the pan and ensure good browning.
You can substitute sirloin for top round for a more tender result, though it is more expensive.
You can substitute ground beef for the steak if desired.
Increasing the steak amount to 2 lbs will increase the protein per serving to about 48g.
