To a cast iron skillet, add about 1/4 cup veggie broth and spray generously with cooking spray. Turn heat to medium, and add the Fideos. Cook over medium high heat and continually stir, turning the noodles over so they can brown on all sides. If you find they are sticking to the pan, add more cooking spray and broth. You do not want too much liquid in the skillet or they will not “brown up”. I let mine get very dry, then add spray, and if that does not help I will add just a splash of broth until they are not sticking. Cook until they are browned and golden. Turn off heat and remove Fideos from the skillet to a bowl or plate.
Remove from oven. Add the lemon zest and juice and a pinch of red pepper flakes. Sprinkle with chopped herbs.
