  1. Feel free to add more or less sazon, according to what you like. 
  2. I used shiitake mushrooms. If you use common mushrooms, they will shrink significantly. If you decide to use them, I recommend doubling the mushroom amount. 
  3. Sazon can be found online at Amazon.com, or at most big-box grocery stores including Walmart and Safeway.
  4. Sofrito can be storebought, but its best fresh and homemade
