Take your choice of these two shortcuts:
1. Cook a big batch of dried beans according to package directions until just tender.
2. Drain, cool, and place in freezer bags or containers in 1-3/4-cup portions (1-3/4 cups cooked beans equal a 15-ounce can of beans). Label and freeze the beans for up to three months.
3. To use, place the beans (thawed or frozen) in a saucepan with 1/2 cup water for each 1-3/4 cups of beans. Simmer, covered, over low heat until heated through. Drain and use.
