Spinach has small leaves that are green to black-green. The deeper the color, the higher nutritional value, so for the biggest nutritional punch pick crisp, dark leaves when shopping. Avoid those with slimy spots. Spinach's slight saltiness pairs well with Bibb lettuce, Boston lettuce, and radicchio.
