In a large pot, cook pasta "al dente" and drain. Also cook 1 or 2 minutes less than package instructions so it is "al dente"

Meanwhile, slice off ends of zucchini and discard. Cut zucchini in half lengthwise. Using a mandoline or large cheese grater, or carefully with a sharp knife, slice zucchini into thin (about 1/8 inch ) slices trying to keep some skin on ribbons for color. Stack slices and if long, cut in half lengthwise. My zucchini's were on the smaller side so I didn't cut them. Reserve zucchini slices in a large bowl.

Add half of the bunch of basil leaves, 1/2 cup vegetable broth, 2 tbsp lemon juice, 2 tsp lemon zest, 1 chopped garlic clove, salt, pepper & red pepper flakes to a food processor and blend to a thick soup consistency. Add more vegetable broth if needed. Set aside. (what you don't use can be saved for later to add to soups, pastas or spread on toasted bread )

In a non-stick skillet, add /2 tsp olive oil heat until hot. Add bread crumbs and saute until brown & crunchy.

In a pasta pot or large deep skillet, heat the olive oil over low-medium heat. Add 1-2 chopped garlic cloves, chopped tomatoes and shallots and cook until soft and translucent but not browned (about 2 minutes). Add 1/8 to 1/4 cup vegetable broth (or more if needed depending on how many zucchini ribbons you have) Bring to boil, lower heat. Add 3 tbsp of basil sauce, zucchini ribbons and cook zucchini for approximately 3 minutes or less. You want it to stay somewhat firm and you don't want too much liquid so add veggie broth gradually. Add parsley, cooked fettuccini (if using), 1/4 cup chopped basil (or more to taste) salt, pepper and toss to combine. I always add more red pepper flakes but I like things spicy. Serve with a big sprinkling of toasted bread crumbs on top for crunch, sliced avocado & fresh sliced tomatoes. Sprinkle avocado & tomatoes with bread crumbs.
