Ensalada de Calabacitas con OreganoZucchini in a light marinade with fresh oregano makes a colorful and appetizing single-ingredient salad presented in the nueva cocina style—with the slices decoratively overlapping on a serving plate. Of course, if you're in a hurry, this can be a fabulously fast and delicious dish to make; just put the cooked slices in a bowl and mix with the dressing. It may not look as striking, but the flavors are still wonderful. Fresh oregano is key here, so reserve this recipe for when you can find it, instead of substituting dried oregano. If cotija cheese is not available, mild feta can be used.
