Spice the salmon and cook in a hot cast iron skillet for 2 minutes and place in a 325 degree oven for 8 - 10 minutes.
In another skillet, heat the olive oil. Add the onions and mushrooms and cook for 3 - 4 minutes. Add the gluten flour and mix well. Next, add in the chicken stock and mix well until sauce thickens. Continuing by adding the pesto followed by the roasted red peppers.
To complete the pasta dish, pour in the noodles. It is also good to add some of the pasta water too. Once mixed, serve by placing in a bowl and topping with the salmon.
