Prepare the zesty Good Seasons Italian dressing mix according to package instructions. Combine with olive oil, vinegar, and water in a bowl, whisking until smooth.

Dice the Roma tomatoes and green onions, removing the seeds from the tomatoes for a cleaner texture.

Chop the cilantro and add to the diced tomatoes and green onions. Mix in the diced jalapeños for an extra kick.

Fold the shredded Colby Jack cheese into the vegetable mixture carefully to maintain texture.

Pour the prepared dressing over the mixture and stir gently to combine without mashing the vegetables.

Transfer the dip to an airtight container and refrigerate for at least four hours, preferably overnight.

After chilling, stir lightly, then serve with tortilla chips or fresh veggies.
