1. The night before, cook your macaroni. Once cooked, drain and rinse in cold water. Put your pasta in a gallon zip lock bag with Italian dressing. Seal and put in the fridge overnight.
2. The next day ….. Cut all your veggies and set aside while you find a very large bowl or pot, whatever works.
3. Mix everything all together. I personally prefer to use my hands. Taste and adjust seasoning to your likings (personally I like a little more black pepper in mine). 
4. Refrigerate for at least 1 hour before serving. 

Eat and enjoy.
