An assortment of tea sandwiches makes a lovely picnic. Some other fillings or open-face toppings might include cream cheese and roasted red bell pepper, prosciutto and julienned sun-dried tomatoes, or thinly sliced cucumber and smoked salmon.

In a small bowl, combine the arugula and cherry tomatoes. Drizzle with the vinegar and olive oil. Season with salt and pepper. Toss to coat.

Spread the olive paste on 4 slices of the bread, spread the goat cheese on the 4 remaining slices. Place the arugula mixture on each olive paste slice and top with the goat cheese slices. Cut diagonally into triangles.
