Saute the onions or shallots in olive oil until soft, add the fresh chopped garlic and quickly saute for a few seconds and set aside
To a high speed blender or food processor, add the peppers, tomatoes, tofu, nutritional yeast, olive oil, salt, 1 packed cup fresh basil, the miso (optional) and the sauteed onions and garlic
Blend all these ingredients together until thoroughly combined and totally smooth
Pour into a saucepan and set aside while you cook your noodles
When your noodles are close to being done, start heating up the sauce on medium low until hot, but don't boil. Right before serving the sauce over the noodles, stir in the fresh lemon juice
When the noodles are cooked, drain and top them with the roasted red pepper sauce and toss and taste. Adjust seasonings and serve topped with a little chopped fresh basil
