Preheat your oven to 350°F (175°C). Grease and flour two 9x5-inch loaf pans, or line them with parchment paper for easy removal.
Combine the sugar, melted coconut oil, eggs, Greek yogurt, and vanilla extract in a large mixing bowl.
Whisk together the flour, baking soda, and salt in a separate mixing bowl.
Gradually add the wet ingredients to the dry ingredients, mixing until combined.
Stir in the Greek yogurt until smooth and well incorporated into the batter.
Gently fold in the diced strawberries until evenly distributed throughout the batter.
Pour the batter into the prepared loaf pans and smooth the top with a spatula.
Bake in the preheated oven for 55-65 minutes, or until a toothpick inserted into the center comes out clean.
Allow the bread to cool in the pan for about 10 minutes, then transfer it to a wire rack to cool completely before slicing.
Top with crumble topping. See instructions below.
