Cut tofu into 1/2" thick rectangles, use 2 tablespoons of your corn starch and coat tofu. Lightly fry tofu 3-4 mins per side and set aside and add salt
Add the other tablespoon of corn starch (or arrow root powder) to 1/4 cup water, mix and set aside. This will help your sauce thicken!
Now add your marsala wine, no chicken broth to the same pan and bring to a simmer, now add your corn starch thickener and let thicken up for about 5-8 mins. Once sauce has reduced by almost HALF you can add your tofu back into your pan and coat your sauce with it.
This is good over potatoes, rice, or make it low carb with steamed cauliflower and served with broccoli or greenbeans!
