I adapted this recipe from Five and Spice for Zucchini Noodles with Tuna and Tomato. Using thin slices of zucchini instead of pasta is a great way to eat more veggies and half your carbs. Not to mention, absolutely delicious. Be careful to use only a few tablespoons of water when you blanch the zucchini.
Otherwise the water is really difficult to drain out (I ended up broiling mine).
Enjoy!
