Prepare the Salad: In a large bowl, combine the romaine lettuce, most of the diced tomatoes, most of the diced red onion, and most of the chopped cilantro. Add ¾ of the dressing to the bowl and gently toss the salad to combine.
Prepare the Tortilla Strips: Cut small white corn tortillas into strips. Fry the tortilla strips in 350°F/180°C oil for about a minute or less. Drain the tortilla strips on kitchen towels. Season with salt while still hot.
