In a large bowl combine the tomatoes, diced sun-dried tomatoes, garlic, and olive oil. Slowly mix in the vinegar. Stir in the oregano, salt, and pepper.
Cut the baguette into ½ inch pieces and place on a baking sheet. Top each crostini with 1 tablespoon of Sabra hummus, 1 tablespoon of bruschetta and then sprinkle with feta cheese.
Bake for 6-8 minutes or until the crostini is crispy and the cheese is starting to brown.
