You most certainly can but they need to be mashed first. Stir in a tad bit of lemon juice (not too much or they'll be too watery) and freeze in individual freezer bags with air removed. I do this whenever they are on sale and they stay in good condition for about three or four months. They're great to use for sandwiches, salad dressing, dip and even mixing with a fresh avocado for guacamole.
