Add chia seeds, almond milk, honey, vanilla, Meyer lemon zest, and kosher salt to a medium bowl, whisking to combine. Whisk 2 more times within a 10 minute period, then cover the bowl with plastic wrap, and transfer to the refrigerator. Let sit overnight (for up to 2 days).

When you are ready to serve, whisk the chia seed-almond milk mixture to break up any lumps. Taste for sweetness, and add additional honey if needed (this shouldn't be too sweet). Top with flaked coconut, chopped pistachios and crystallized ginger.
