Chorizo Mac

In a large pot, boil some water, with a dash of salt and a little drizzle of olive oil.

In a separate pan warmed up over medium heat, put the 1/4 teaspoon of olive oil and the onions in. Cook for about 3 minutes, until the onions start to become translucent. Add the chorizo. Cook for an additional 5-8 minutes, until the chorizo is browned and no longer looks pink (it will still have a rather mushy consistency).
Remove from heat and set aside.

Once the water is boiling, add the macaroni noodles. Cook according to package directions or until they are finished per your preference. Then drain and set aside.

Use a small saucepan and melt the butter over medium heat. Add the flour. Stir, making sure the butter has absorbed all of the flour. Slowly add the milk in, whisking away any lumps that may appear. Once the milk is incorporated and any lumps are gone, add the cheese.
Cook until the sauce has thickened.

Put the cooked macaroni noodles back into the large pot, minus the water. Add the cheese sauce. Add the cooked chorizo and onion mixture. Stir well and enjoy!
