Line an 8x8 baking pan with parchment paper.
In a large mixing bowl, whisk together oats, flour, cinnamon, ginger, salt, and brown sugar.
Pour in melted butter and vanilla extract and stir until all the ingredients are combined and clumps start to form.
In a separate bowl, toss the strawberries in lemon juice.
Sprinkle strawberries with sugar and stir.
Pour half the crumble mixture into the baking pan and press firmly to form an even layer.
Scatter strawberries on top, reserving ¼ cup.
Sprinkle remaining half of the crumble mixture over strawberries, then add remaining ¼ cup of strawberries.
Bake in 375° oven for 35-40 minutes until golden & bubbly.
Allow to cool before cutting into bars.
