Preheat your oven to 350F
Lightly coat a pot with oil and cook your onions, celery, and garlic for about five minutes.
Once cooked, add your chorizo and seasoning. Chop the chorizo up as it cooks. It should be fully brown after about five minutes.
After, add a cup and a half of water and bring it to a boil.
Once boiling, turn off the heat and stir in your stuffing mix until all the water is absorbed. Fluff with a fork. Cover and let it sit for about five minutes.
Once your chorizo stuffing has absorbed the water and has become fluffy, move it onto an oven safe casserole dish. Place it in the oven at 350F for 10minutes, until the top is slightly golden.
While it is baking, make your chimichurri.
After ten minutes, take the chorizo stuffing out of the oven and drizzle the chimichurri on top.
Serve and enjoy!
