Creating the Southwest Zucchini Noodle Mason Jar Salad with Avocado Dressing is straightforward. Just follow these simple steps:

1. Prepare the Zucchini Noodles: Use a spiralizer to create zucchini noodles. Set them aside in a large bowl.
2. Dice the Vegetables: Chop the cherry tomatoes, bell pepper, and red onion. Add them to the bowl with zucchini noodles.
3. Add Corn and Black Beans: Mix in the corn and black beans, combining everything gently to stay intact.
4. Make the Avocado Dressing: In a small bowl, mash the avocado with a fork. Add lime juice, minced garlic, cumin, chili powder, salt, and pepper. Mix until smooth and creamy.
5. Assembly in Mason Jar: Start with a layer of the avocado dressing at the bottom of the jar, followed by a generous helping of the zucchini noodle mixture. Continue layering until the jar is filled, ending with a layer of veggies on top. This will help keep the dressing from leaking.
6. Garnish: If desired, sprinkle fresh cilantro on top for an added burst of flavor.
7. Seal and Store: Put a lid on the mason jar to keep everything fresh. This salad can be stored in the fridge for up to 3 days.
8. Ready to Serve: When you’re ready to eat, simply shake the jar a bit to mix in the dressing, or pour the contents into a bowl for a fancier presentation.

With these easy steps, you can customize your salad every time to suit your taste or what you have on hand.
