4-5 Large Roma Tomatoes (these are best because they are "meaty" and have less water than other varieties)
1 bunch Green Onions, sliced thin (use both the white and green parts)
1 to 1.5 cups Shredded Cheese (Sharp Cheddar or Monterey Jack work best for that classic homestyle flavor)
1/3 cup White Vinegar or Apple Cider Vinegar (adjust based on how "strong" you want the base)
1 tablespoon Vegetable or Olive Oil (this helps the vinegar coat the cheese and tomatoes without making them soggy)
1 teaspoon Salt (to taste)
1/2 teaspoon Coarse Black Pepper (a traditional "salsa" often uses chili peppers, but in this vinegar-based version, black pepper provides the main kick)
Optional: A pinch of sugar (to balance the vinegar) or a dash of garlic powder
Instructions
Prep the Tomatoes: Dice the tomatoes into uniform chunks. To keep it from getting saucy, place the diced tomatoes in a colander for about 10 minutes to let the excess juice drain away.
Mix the Dressing: In a small bowl, whisk together the vinegar, oil, salt, pepper, and sugar (if using). This ensures the flavors are fully incorporated before they hit the vegetables.
Combine: In a large mixing bowl, combine the drained tomatoes and the sliced green onions.
Add the Cheese: Fold in the shredded cheese. Doing this before the dressing helps the cheese get "pickled" slightly by the vinegar later.
Marinate: Pour the vinegar mixture over the tomato and cheese blend. Toss gently with a spoon to coat everything evenly.
Chill: Cover and refrigerate for at least 30 minutes. This is the most important step; the vinegar needs time to slightly soften the onions and "cure" the tomatoes while keeping them firm.
Tips for the Right Consistency: The "Not Saucy" Secret: If you find the dish is still too watery, remove the "guts" (seeds and pulp) of the tomatoes before dicing. Only use the firm outer walls of the tomato. The Cheese: Use "thick cut" or "farmhouse" shredded cheese if available. The very fine, powdery pre-shredded cheese can sometimes clump too much in a vinegar base. The Vinegar: If you want it exceptionally sharp, use straight White Distilled Vinegar. If you prefer a slightly fruity or mellow back-note, try Apple Cider Vinegar.
Serving Suggestion:
This is best served with sturdy, salty tortilla chips or even thick corn chips (like Fritos), which stand up well to the weight of the cheese and firm tomato chunks.
