Start by washing and chopping the cucumbers, red bell pepper, and orange bell pepper into bite-sized pieces. Finely dice the red onion and roughly chop the fresh cilantro. If you're using corn from the cob, cut the kernels off, or if using frozen, thaw it. Combine all these vibrant ingredients in a large mixing bowl.

In a separate mixing bowl, whisk together the freshly squeezed lime juice, olive oil, chili powder, salt, and pepper. Ensure the ingredients are well combined and the dressing is smooth.

Pour the prepared dressing over the bowl of chopped vegetables. Gently toss everything together until each piece is beautifully coated in the zesty dressing.

Cover the mixing bowl with plastic wrap or transfer the salad to an airtight container. Place it in the refrigerator for at least 15-30 minutes to let the flavors meld together.

When ready to serve, give the salad a gentle toss to redistribute its ingredients. Scoop into a serving bowl and enjoy cold.
