Step 2
Shred zucchini using the large holes of a box grater. Squeeze dry in a clean kitchen towel (you should have about 2 cups). Heat oil in a large nonstick skillet over medium-high heat. Add the zucchini, beef, chili powder, onion powder, cumin and salt. Cook, stirring, until the beef is cooked through, 5 to 7 minutes.
