You'll need this:
2 small cans diced black olives
2 small cans diced green chiles
4 green onions, chopped (green & white parts)
3 tomatoes, seeded and chopped
3 TBSP red wine vinegar
2 TBSP olive oil
kosher salt & black pepper to taste
Combine all of the ingredients in a bowl and toss. Taste for seasonings.
Cover and refrigerate several hours or overnight. Serve with tortilla chips.
I have very fond memories of Beaumont. Maybe it was the food.
