Add the chopped zucchini to a large pot. Pour the lemon juice in, and gently toss to combine.
8 cups peeled, seeded, & diced zucchini, 2/3 cup lemon juice
Cook the zucchini, stirring often for 15-20 minutes- until they're soft, tender, and have gone from white to resembling cooked apple slices.
Once cooked stir in the sugar, cinnamon, nutmeg, and cloves. Let the mixture simmer for roughly 2 minutes, just until the apple slices are infused with the flavors.
1 cup sugar, 1 1/4 tsp ground cinnamon, 1/2 tsp ground nutmeg, pinch ground cloves
Taste it and see, but the zucchini mixture will now look & taste like apple pie filling. Transfer the filling to a waiting 8x8 dish.
