This includes radicchio, endive, frisee and escarole — bitter, leafy veggies that come in a rainbow of colors.

Look for endive with tight heads that feel heavy for their size. All endive varieties should be free of black or mushy spots, with very few (to no) brown or wilting leaves.

There are several varieties of mushrooms and they can be purchased fresh or dried. Look for fresh mushrooms without slimy, moldy or black spots.

Radicchio is a bitter leafy vegetable. Radicchio di Chioggia, the most common variety, resembles a small red cabbage, but radicchio comes in a variety of other shapes. In all cases, it should be crisp and unwilted.

Rapini, or broccoli rabe, looks like a leafier version of broccoli. Both the leaves and florets should be deep green without yellow spots.

Although you can sprout many seeds, the two most common sprouted types are bean and alfalfa. Look for sprouts that are perky and smell fresh. Avoid any that smell off or that appear slimy or wilted.
