Using a spiralizer, create noodles out of the zucchini OR buy pre-packaged zucchini noodles.
Blend the avocado (saving some for garnish, if you so choose), water or dairy-free milk, lemon juice, basil, salt and pepper until smooth.
Pour the creamy avocado sauce over the noodles.
Add the corn and grape tomatoes.
Optional: garnish with more basil and avocado slices. I've garnished with chives too (as shown above) and it was also yum.
