Preheat the oven to 350°F and prepare a loaf pan by greasing it with butter or oil.
In a large bowl, combine the white whole wheat flour, baking powder, and salt. Mix well and set aside.
In another bowl, beat the eggs, then add the Greek yogurt, sugar, vanilla extract, and melted coconut oil. Mix until smooth.
Gradually pour the wet ingredients into the dry ingredients, stirring until the batter is well mixed and smooth.
Gently fold in the diced strawberries and chocolate chunks until evenly distributed in the batter.
Pour the batter into the prepared loaf pan, spreading it out evenly.
Bake in the preheated oven for about 55 minutes, or until a toothpick inserted into the center comes out clean.
Remove the bread from the oven and let it cool in the pan for at least 10 minutes before transferring it to a wire rack to cool completely.
