Keep growing medium moist. Cut as needed, but before plants become too old and tough. Buckwheat, peas and sunflowers cut only once. Spent soil and roots can be composted or dug into the garden. These crops can also be grown in baskets or tray type sprouters.
Baskets are more trouble to clean and sanitize.
Sunflowers grown in a perforated tray without soil really do well with wet feet. Grilled Cheese - liven up a grilled cheese sandwich with your favorite sprouts and a tomato slice. Tacos - Use sprouts instead of shredded lettuce in tacos. Sandwiches, Subs and Pitas - sprouts are a delicious addition to any of these. Salads - add fresh sprouts to just about any salad, or create your own sprout salad.
