Fill a large pot with water and 1 tablespoon salt. Add 12 ounces pasta of choice to the pot, stir occasionally and cook pasta according to package directions. Drain the pasta (no need to rinse) through a colander. Set drained pasta aside (it can stay in the colander).
To make the Pesto, blend all Pesto ingredients in a high-speed blender or food processor until smooth for 2 minutes: 2 cups fresh basil leaves, 2 cups fresh spinach leaves, ¼ cup walnuts, ¼ cup grated parmesan cheese, 1 tbsp lemon juice, 2 garlic cloves, ¼ cup extra virgin olive oil, ½ cup canola oil , and ¾ teaspoon salt. If it’s having a hard time blending, pause blending every so often and use a spoon to move things around in the blender and blend again.
Prepare the 10 ounces solid white albacore tuna by draining the water from the can. Place the tuna into a large mixing bowl and flake it into small pieces using a fork.
Add the cooked pasta, ½ pint cherry tomatoes (halved) and pesto to the flaked tuna. Mix together until pasta is well coated.
Taste and adjust salt to your liking if necessary.
Garnish with 1 tablespoon Lemon zest and 1 tablespoon Grated parmesan before serving.
