5. Make a baller grain salad
Grains are great. They’re healthy, filling, easy to cook, are delicious hot or cold, and last throughout the week -- oh, and did I mention cheap? They’re so cheap. Cook up a cup of quinoa, farro, or wheat berries and let cool. Then toss it with some olive oil, aged balsamic vinegar, and a lil’ salt and peppa. This salad gets better with time so you can bring a batch of it to work and then use different mix-ins each day, like feta cheese, roasted peppers, and scallions; or grilled chicken, arugula, and walnuts.
