Here is one of my favorite recipes from when I was little. I don't know exactly where it comes from, but I saw a Korean dish in a magazine once that was similar but had scallions.
You can serve these warm or cold, and they're even good as a sandwich with two pieces of crunchy whole-grain bread.
Zucchini pancakes (makes 10 small cakes)
2 cups shredded zucchini
1/2 a small yellow onion, shredded
1 egg yolk
1 cup all-purpose flour
4 tablespoons canola oil, divided
salt and pepper, to taste
1.) Combine zucchini, onion, egg, yolk, and flour in a mixing bowl, and stir well with a fork.
2.) Heat half the oil in a medium nonstick skillet on high.
3.) Drop heaping spoonfuls -- about 1/8 cup each, I'd say -- of the batter into the oil. (Make about 5 pancakes at a time, if you can.)
4.) Cook cakes for about 3 minutes a side, or until they are a medium golden brown. As the oil gets hotter with each skilletful of cakes, this time may decrease.
5.) Transfer to a plate lined with a paper towel, and drain briefly before sprinkling with salt and pepper and keeping pancakes warm in the oven.
6.) Repeat with another round of cakes.
