Combine masa and water until it makes a loose paste, pour into chowder stirring vigorously. Cook for another 10 minutes. At this point if you have an immersion blender take your blender and give the chowder a few whizzes around the pot. You don’t want the chowder to be smooth you just want to break up a little bit of the vegetables to make for a smoother, thicker soup.** If you don’t have an immersion blender, have no fear, just take 2 cups of soup and put it in your blender and blend until smooth, add back to the pot.**Continue to cook for another 10 minutes, taste and add 1 teaspoon of salt or more if needed, as well as a good teaspoon of fresh cracked pepper.
Just before serving add 3/4 cup of feta cheese stir. Serve topped with additional feta and bacon crumbles.
