Begin by chopping the seedless cucumbers, red and orange bell peppers, red onion, and fresh cilantro into bite-sized pieces. Combine all chopped ingredients in a large mixing bowl.

In a separate small bowl, whisk together the fresh lime juice, olive oil, chili powder, salt, and pepper until well combined and emulsified.

Pour the dressing over the mixed vegetables, ensuring every piece is evenly coated. Gently toss the salad.

Cover the bowl with plastic wrap and refrigerate for 15 to 30 minutes to allow flavors to meld.

Once chilled, give the salad a final gentle toss before serving. Enjoy as a side dish or with tortilla chips.
