Preheat your oven to 400 degrees. Drizzle the olive oil over the tomatoes and roast them in the oven for 10 minutes, or until they are soft and a few have burst.
While the tomatoes are roasting, place a colander in your sink and put a pot of lightly salted water on the stove and bring it to a boil. Once it begins to boil, drop the zucchini noodles in, wait 30 seconds then drop in the 2 cups of spinach and stir the pot. Immediately pour the noodles and spinach into the colander and let it drain well.
Combine all the pesto ingredients in a blender and blend on high until smooth. Pour the pesto over the well-drained zucchini noodles and toss to coat. Season to taste with sea salt (We like about one teaspoon).
Serve the zucchini noodles with the burst tomatoes and a few sunflower seeds over top.
