In large saucepan, over medium-high heat, sauté onion in olive oil until soft, about 15 minutes, stirring every few minutes.
Add the fresh tomatoes, jarred tomatoes, tomato paste, garlic, basil, thyme, sea salt and pepper. Bring to a boil, then reduce heat and simmer 15-20 minutes, uncovered, until the liquid is almost evaporated. Stir occasionally.
Preheat oven to 375 degrees. Grease a pie plate. Set aside.
In large bowl or blender, beat together warm parsnip puree, coconut cream, eggs, sea salt and pepper. Combine until mixed thoroughly. It will be thick and smooth.
Pour puree into greased pie plate. Use a spatula to distribute the puree, so it’s slightly concave, and higher around the edges.
Ladle the tomato sauce around the center, spreading it to within an inch or so of the edge, so the parsnips create a border.
Fan tomato slices around the center of the pie, decoratively overlapping them.
Bake in preheated oven 30 minutes.
Remove from oven. Optionally garnish with sautéed shallots, garlic and fresh basil.
Serve!
