Feta Tomato Topper

I couldn't think of an appetizer to make for Bunco. My friend, Teresa, gave me this recipe and promised it would be good. She was right! There were none left at the end of Bunco. :)

1 cup (4 oz) crumbled feta cheese (can also use tomato basil feta cheese)
1 cup plum tomatoes, seeded and diced (about 3 medium tomatoes)
1/4 cup finely chopped red onion
1/4 teaspoon freshly ground pepper
1/4 teaspoon dried oregano
2 tablespoons extra virgin olive oil
approximately 36 melba crackers

In a bowl, combine first 6 ingredients. Spoon 1 tablespoon mixture onto each melba cracker.
