Watermelon is a cool and refreshing summertime treat but dealing with those pesky black seeds can be annoying. Instead of tossing (or spitting) them out, however, turn them into the perfect snack food. Roasted watermelon seeds are reminiscent of popcorn (mainly the unpopped kernels) and have a sort of caramel-like taste. After toasting them on the stove, you cook them in a bit of salt water, giving them a satisfying salty flavor; alternatively, you can roast them in the oven and then add cooking spray and salt. Try these crunchy seeds in place of sunflower seeds or peanuts for your next snack.
