Zest of 1 Meyer lemon
Juice of 1 Meyer lemon
3/4 cup white sugar 150 g

Directions
- Make the pie crust dough by placing the flour, sugar and salt in a large bowl. Cut the cold butter into 1/2-inch cubes and add to the dry ingredients. Using your fingers, toss the cubes in the flour then smash them into flat pieces, continue to dip your hands in the flour to prevent the butter from sticking. You want to break the butter down into pieces roughly the size of a pea.
- Once all the butter is flat and broken up, drizzle 4 tablespoons water over the dough and toss with a fork until a dough starts to form. Using your hands, massage the dry ingredients into the wet parts. If the dough looks too dry, add more water, half a tablespoon at a time, until a cohesive shaggy dough forms.
- Gather the dough and flatten it into a 1-inch thick piece. Wrap with plastic wrap and then refrigerate for a minimum of an hour or overnight (or up to 2 days in the fridge).
- While the dough is chilling, make the crumb topping by chopping or crushing the pistachios (in a freezer Ziploc bag). Add them to a bowl with the flour, oats, white sugar, brown sugar, turbinado sugar, cinnamon, ginger, and salt. Drizzle the olive oil over all the ingredients and toss with a fork until it starts to clump up and is absorbed by all the dry ingredients. Cover and refrigerate until you are ready to assemble the pie.
- When the dough has fully chilled, preheat the oven to 375°F. If you’re using a 9 x 13 x 2-inch baking pan (the kind that you make brownies in), lightly spray it with cooking oil, then line it with parchment paper. If you are using a 9 x 13 x 1-inch rimmed baking quarter sheet, skip this step. Flour a clean surface and then roll out a disk of dough into an 11 x 15-inch rectangle.
- Move the dough to the baking pan, tucking it into the sides, and then gently curl or crimp the edges of the dough. Place the dough in the fridge to chill (no need to cover it) while you make the filling.
- Make the filling by combining the rhubarb, strawberries, chopped kiwis, lemon zest, lemon juice, cornstarch, olive oil, vanilla, cinnamon, pepper, and salt in a large bowl. Toss with a spatula until all the ingredients are evenly coated and the cornstarch is absorbed.
- Take the chilled rolled out dough from the fridge and pour the filling into it, making sure to scrape out any liquid that accumulated at the bottom of the bowl. Spread the filling out evenly over the crust. Place the pan on a large baking sheet (to catch any drips) then bake in the oven for 30 minutes.
- Once the 30 minutes is up, pull the pie out of the oven and sprinkle the cold crumb topping over the top of the fruit, making sure to evenly distribute the topping all over. Break up any large chunks with your fingers but keep some of the smaller chunks together.
- Return the pie to the oven and bake an additional 30 to 40 minutes or until the fruit is bubbling through the crumb topping and the crumb topping is golden brown. If the topping is browning too fast but the filling isn’t bubbling yet, cover the pie with aluminum foil and continue to bake until the filling is done.
- Let cool completely before serving. You can server the pie by itself or with a scoop of vanilla ice cream.
