Halve your tomatoes and place them in a shallow bowl. Add the vinegar, oil, garlic and then sprinkle with salt and pepper. Let tomatoes sit one hour. Do not refrigerate as this will make the tomatoes mushy.

Halve your tomatoes and place them in a shallow bowl. Pour over the vinegar, oil, garlic and then sprinkle with salt and pepper. Let tomatoes sit one hour. Do not refrigerate as this will make the tomatoes mushy.

Meanwhile, mix together the two cheeses until smooth. Refrigerate until tomatoes are ready. Toast your bread in a skillet, in the oven, or over a grill pan. Spread about 1 tsp. of the cheese mixture over your bread, top with a few pieces of arugula, and then one tomato. Repeat until you use all the slices. Drizzle the remaining tomato marinade over the crostini right before serving. Enjoy!
