Freezing Fresh Herbs and Spices

When I get parsley, chives, and other fresh herbs from the grocery store, I usually use only about a tbsp or two, and I am left with a lot! Sometimes I also have celery sticks and bell peppers (leftover from parties) that I would hate to waste by throwing away. So, I store them for later use in making soups or spicing up sauces by chopping them, putting them in ice cube trays, filling with water then freezing. When they have turned into ice cubes, I place them in resealable plastic bags (grouped accordingly), ready to be used anytime! (It's the same thing I do with my frozen beef broth pre-measured at 1-cup amounts.) It sure saves time and money!
