Step 1
Start by heating some oil in a large skillet over medium heat. Toss in the beef and cook it for about 4 minutes, breaking it up as it browns. Turn the heat up a bit to medium-high, then sprinkle in the taco seasoning and a pinch of salt. Keep stirring for a couple more minutes until the meat is nicely browned. Next, add the tomatoes, beans, corn, and a splash of water. Let everything come to a gentle simmer, stirring now and then, until the sauce thickens slightly—this should take around 5 minutes. Once that's looking good, stir in the zucchini, lower the heat to medium-low, and cover the skillet. Cook until the zucchini is just tender, which usually takes about 3 minutes. Serve it up in bowls and finish each one with some cheese and chopped green onion on top.
