In a bowl, whisk together 1 cup Greek yogurt, ⅔ cup milk, 3 tablespoons honey, 1 teaspoon lemon zest, and 1 teaspoon vanilla extract until smooth.
Stir in 4 tablespoons chia seeds until evenly combined. Make sure there are no clumps so the pudding thickens evenly.
Transfer it to single-portion jars or leave it in the mixing bowl. Cover and refrigerate for at least 2 hours, or overnight, until the mixture turns thick and creamy.
Before serving, give it a quick stir. Top with fresh fruit, nuts, or a drizzle of honey and enjoy cold.
