Heat a large skillet over medium-high heat and drizzle with olive oil. Add ground beef to the pan and begin breaking down using a potato masher or wooden spoon. Sprinkle in taco seasoning mix and cook until beef is browned about 8-10 minutes. During the last minute or so of cook time, add in the corn and heat until warmed through; remove from heat and set aside.
To assemble taco salad bowls, fill four bowls with two cups of lettuce of cabbage as a base. Top with equal parts beef and corn mixture, red onion, tomato, avocado, and tortilla chips. Garnish with cilantro, lime and jalapeno slices if you wish.
Notes
I don't typically use a dressing with this salad as the beef is flavorpacked and the creamy avocado becomes a bit of a dressing when I mix everything together. If you wish to drizzle with dressing I recommend my honey lime vinagirette recipe. Swapping out guacamole for the plain avocado or pico de gallo for the tomatoes and onions is always a good idea.
