In a large frying pan over medium heat cook the onions and peppers until softened. Add the broccoli and zucchini. Cover and cook over medium low for ten minutes or until the broccoli is tender. Remove the veggies from the frying pan and put them in a medium sized serving bowl.
Return the frying pan to the stove and cook the shrimp over medium heat until curled up and pink. Add the shrimp to the bowl with the veggies.
Return the frying pan to the stove and add the butter, cream, and cheese. Cook until the cheese melts. Sprinkle the gluccomannan over the top and whisk in, if using, to thicken the sauce.
Return the shrimp and veggies to the frying pan and gently fold them into the sauce. Put into individual bowls and sprinkle with extra cheese if desired.
Can add ¼ teaspoon gluccomannan (optional, used to thicken the sauce)
