Lay the tortilla or flatbread on a clean counter. Spread about a tablespoon of sun-dried tomato pesto over the surface of the bread, leaving about a 1/2-inch at the edges. Repeat with a tablespoon or two of the hummus. Top with a small handful of field greens, followed by an even layer of the cucumber, tomatoes, olives, roasted peppers and finally the feta cheese. Tightly roll the wrap and lightly press to secure. Carefully slice in half with a slightly diagonal cut. Repeat with the remaining bread and ingredients. Serve immediately.
