Heat the oil in a large skillet over medium high heat. Add the ground beef and cook, breaking up the meat with a wooden spoon, until no longer pink, 5 to 7 minutes. Drain off excess fat and return to the skillet. Reduce the heat to medium-low and sprinkle in the taco seasoning. Toss to coat. Remove from heat.
Assemble the Bowls:
To serve, divide the beef mixture between 4 bowls along with the rice, romaine, radish, avocado, cherry tomatoes, cilantro, and crushed tortilla chips.
