Mushroom

Grilled knockwurst goes well with yellow or Dijon mustard and soft pretzels. The knockwurst will char quickly on the grill; be sure to turn it frequently.

Similar greens—such as yow choy, also known as choy sum (which looks almost identical to bok choy but bears small yellow flowers), broccolini, or even regular broccoli—will work well in this dish if you can’t find Chinese broccoli. You can buy wide rice noodles at Asian grocery stores, or use the narrow rice noodles (often labeled “pad thai noodles”) that many supermarkets carry.

We topped these burgers with smoked Cheddar cheese, but you can use another type of cheese, or omit it entirely. To clean the mushroom caps, wipe them with a damp paper towel; do not rinse or soak them because they will remain soggy even after cooking.

To julienne the vegetables, cut them into thin matchstick-size pieces using a sharp knife or a mandoline. Refrigerate them in an airtight container until ready to use, up to 3 hours.

If fresh is unavailable, look for packages of prewashed baby spinach. Blood oranges are named for their vivid red-streaked flesh.

Some varieties of noodles suggest soaking them in boiling water instead of cooking them; check your package instructions before preparing them.

For a velvety smooth texture, pass the soup through a fine strainer after the mixture has been processed and before adding the cream.

This recipe will serve four as a first course or light lunch. To serve the noodles as a meal, add a few cups of diced firm tofu or cooked chicken breast to the simmering broth in step 3.

You can easily double this recipe and refrigerate leftovers in airtight containers for up to 3 days. The soup can also be frozen for up to 3 months. We used French lentils, but other types of lentils may also be used.
