Parmesan Squash Cakes

I don't recall where I found this recipe.  Given that it's typed out on half a sheet of paper, my guess is I picked it up at the Farmer's market last summer.  I wouldn't bother cutting the paper, so it's not something I found online and printed.  I'll copy it here, with my additions/suggestions in purple.

1 large egg (I used 2)
2/3 cup finely chopped sweet onion (I didn't have that much, but it was plenty-maybe 1/3 cup)
1 T finely chopped flat leaf parsley (I used dried)
1/4 t salt (I didn't measure, just added)
1/4 t pepper (same here)
2 cups shredded summer squash, 2-3 medium (I used 3 that I considered small and ended up with way more than 4 cakes, as the recipe indicates)
1/2 cup freshly grated Parmesan cheese (once again, I didn't measure, I had a small chunk and used it all)
1 T extra virgin olive oil (I needed more)

1. Preheat oven to 400°F
2. Beat egg in large bowl-I started with one, it wasn't enough for the amount of squash I had.  Stir in onion, parsley, salt and pepper.
3. Place shredded squash in clean kitchen towel and gather up ends and twist to squeeze out as much water as possible.  I let my son do this part, only I told him to simply press on the towel to get the water out.  I didn't explain that the goal was to squeeze out water, so he felt the job was done when he had flattened out the mound.  I should have checked.
4. Add the squash and cheese to the bowl, stir to combine.  This is where I realized I needed another egg, so beat one and added.
5. Heat oil in large skillet over medium heat.  Pack a 1/3 cup measuring cup with the mixture and unmold into the pan.  Gently pat it down to form a 3 inch cake.  Repeat, making 4 cakes.  I now see the flaw in the recipe.  If you start with 2 cups of squash, and just use 1/3 cup scoops, you will get 6, not 4.  I got 9, so I guess I had more than 2 cups of squash!
6. Cook until brown and crispy on the bottom, 3-4 minutes, then gently turn over and transfer pan to oven.  Bake for 10 minutes and serve immediately.  I don't have a skillet that can go into the oven, so I oiled a cookie sheet and transferred them to that.  As the water didn't all get squeezed out, they kinda fell apart, but they tasted good!
