Preheat oven to 400ºF and line a baking sheet with parchment paper.
Making your Pesto – in a food processor or blender add walnuts, olive oil, lemon juice, half of the baby spinach, basil, sea salt and black pepper. Blend until smooth. Once smooth take out of blender and put in holding container, aka jar or plastic container.
Finely chop the remaining baby spinach.
Place tortillas on the baking sheet with parchment paper. Add as much pesto as you would like then top with cherry tomatoes, goat cheese and chopped spinach.
