Here is an Italian-inspired recipe that uses store-bought or homemade pesto to season farro, which is then tossed with fresh spinach, roasted tomatoes, red onions and mozzarella for a complete vegetarian meal. Make it with fresh-from-the-market cherry tomatoes when they’re in season, but during the rest of the year, use grape tomatoes, as they tend to be more flavorful than cherry during the colder months. If you’d like, substitute arugula, or cooked broccoli rabe or kale, for the spinach. It tastes delicious warm or cold the next day — and topping it with shrimp, chicken or scallops can make it feel new again. Before reheating, add a bit more spinach, drizzle it with a little olive oil and give it a good stir.
