Preheat your oven to 350°F (175°C) and lightly grease a 6-inch tart pan or small oven-safe dish.
In a small mixing bowl, combine the rolled oats, almond flour, egg whites, and sea salt, stirring until a crumbly dough forms.
Press the oat mixture firmly and evenly into the bottom of the prepared tart pan to create a solid base.
Bake the crust for 12-15 minutes until it is fragrant and the edges are lightly browned, then remove from the oven and let it cool completely.
While the crust cools, place the Greek yogurt, cottage cheese, lemon juice, honey, and vanilla extract into a blender or food processor.
Blend the mixture on high until it is completely smooth and reaches a thick, creamy consistency.
Pour the lemon cream filling over the cooled crust and spread it evenly to the edges.
Wash and slice the fresh strawberries, then arrange them in a decorative pattern over the cream layer.
Garnish the tart with fresh lemon zest and serve immediately or chill for 30 minutes for a firmer texture.
