I heated a cast iron pan on medium low (3 of 10) and on another burner put a pot of salted water on to boil.
In the cast iron pan, I tossed in a pinch of fennel seeds, about 1/4 tsp or so and let them heat while I removed the casings from 3 breakfast sausage links. I added the sausage and, using a fork, smashed it up to little bits of pork. There was not much fat, but it was enough to cook this without any additional oil. I added 2 TBSP of diced yellow onion. Then I diced a small Roma tomato and added it. I let them cook.
I added 3 handfuls or 3/4 cup of dried egg noodles. I ended up with about 1 cup of noodles when it was done cooking.
I added 1/4 cup of sour cream to the cast iron pan, strained the pasta and stirred it into the sauce and then added a big handful, a cup or more, of fresh rocket. I stirred and removed from the heat so it just warmed but did not cook the rocket.
Grate just a bit of asiago or parmesan cheese on top.
This made one serving. It has a peppery flavor from the rocket, a bit of heat from the sausage and this wonder deep flavor coming from the fennel. The sour cream gave it a nice creaminess and added some fat that it really needed to soften the acidity of the tomatoes and the peppery rocket.
