Mix Together:
1 diced tomato
1 diced, seeded cucumber (I like to peel some of the tough skin off, about half of it)
1 diced half red onion
1/2 cup Trader Joe's Herb Crumbled Feta, or other feta cheese
Splash of unrefined extra-virgin olive oil

It's  hot outside, and more fresh, raw fruits and vegetables can be eaten.  A salad once a day is just fine.  It's often humid, or damp, outside, so it is best to avoid foods that produce and attract the dampness into the body, which causes feelings of heaviness, bloating, and even achiness or fatigue.  Avoid damp-producing foods like fried foods, high-fat dairy, excess wheat/bread, and icy/frozen foods and drinks.  Some foods promote urination and "drain dampness," as we say in Chinese medicine.  You can try to emphasize these foods, which include cucumbers, watermelon, celery, dandelion greens, barley, brown rice, mung beans, and chamomile tea.  Don't forget to drink water, but avoid ice water with your meals, which inhibits digestion and promotes dampness and fatigue.
