Hemp seeds. Yes, they're legal and, no, you won't get high. More importantly, these little nutritional powerhouses are rich, nutty, and delicious.Hulled hemp seeds are soft and somewhat chewy (a bit like cooked quinoa), with a creamy, nutty flavor similar to pine nuts and sunflower seeds. My favorite way to eat hemp seeds is in pesto as a substitute for nuts. They can also be tossed into baked goods and smoothies, sprinkled on top of salads and yogurt, and used to make homemade protein powder and hemp milk.
Although members of the same family, the variety of cannabis used for food and the variety used for marijuana are different plants.

It's still illegal to grow any kind of hemp in the US, so most hemp seeds are grown in Canada. Look for bulk or packaged hemp seeds at places like Whole Foods, or order them online from a source like Bob's Red Mill. To maintain freshness, store them in the refrigerator or freezer.
