Preheat oven to 375F (190C).

Heat a large skillet on medium heat and add the ground beef and break apart with a spoon. Once it starts to brown, add in the taco mix.

Meanwhile, slice zucchini in half lengthwise and use a spoon to scoop out the insides and discard them.

Place the zucchini on a baking tray and fill with the cooked beef mixture. Bake for 15-20 minutes.

Top with avocado and tomato and serve.

Meal prep note: Cook meat ahead of time and store in fridge in airtight container. Start at step 3 for future days.
