1. In a pot, bring water and a dash of salt to a boil. Meanwhile, wash produce under water and chop mushrooms and chicken sausage. 

2. Once water boils, cook pasta as directed on the box. Strain when cooked through, and save 1/2 cup of the pasta water. 

3. In another small pot, add the sauce ingredients, and cook on medium-low to heat up. Whisk for two minutes, as the sauce should slightly thicken.

3. In a frying pan, heat 1 tbsp oil. Then sauté the mushrooms until they have a golden brown color. Then add the tomatoes and chicken sausage into the pan. Cook until some of the tomatoes start to burst. Take off the heat.

4. Mix the sauce with the tomatoes, chicken sausage, mushrooms, pasta, and arugula. 

5. Serve and enjoy!
