Add the onion, jalapeno, garlic, and corn to a sauté pan over medium heat. Cover with a lid and sauté until the onions are soft, stirring occasionally.
Dice the tomatoes and cilantro and set aside.
Use a spiralizer or vegetable peeler to create 'noodles' out of the zucchini. Once the onions are cooked, add the noodles to the pan, and turn off the heat. Without stirring, put the lid on and let them gently steam.
Add the broth, avocado, lime, and red pepper flakes to a blender. Blend until smooth.
Transfer the noodles and vegetables to a large mixing or serving bowl. Pour the dressing over the noodles and toss well.
Mix in the fresh tomatoes and cilantro. Serve and enjoy!
