* rice paper (available in the Asian food section of your grocery store)
* rice vermicelli noodles (available in the Asian food section of your grocery store)
* carrots (cut into thin strips)
* cucumbers (cut into thin strips)
* spinach
* green onions (chopped)
* Thai sweet chili sauce (optional)

Soak the vermicelli in water.
Pour boiling hot water into a plate or dish - not too deep of a dish, though. Gently slide the rice paper into the boiling water, and wait until it is "cooked" (about 10 seconds or so - it should no longer be hard and rigid).
Place the wet rice paper on another place, and fill with the vermicelli, carrots, spinach, cucumber, and green onions.
Bring bottom of rice paper up, and fold left side over.
Roll the rest of the spring roll tightly.
Place in fridge for a couple of hours.

Use the sweet chili sauce as a dip.

You can use other veggies if you'd like, or subtract ones from this list.
