I followed the instructions on the Post Punk Kitchen Blog.
We tried both baking and cooking in a cast iron skillet. I think I prefer these in the skillet, rather than baked, only because they came out much faster.
These burgers were really good. They were even better the second day. I will be making these again and again. Note the long times until dinner is on the table. We made the lentils the night before so we didn't have to wait for them to cook on the day of. I want to mess with the texture because we added a ton of bread crumbs to the mixture and even an egg to see if we could get it to form up better, but it did not. Once it was cooked, it held up fine on the bun, but it was soo soft before cooking.
