Preheat oven to 350°F and line mini loaf pans with parchment paper or lightly grease.
In a large bowl, whisk together flour, salt, baking powder, and baking soda until evenly combined.
In a separate bowl, whisk almond milk, applesauce, melted butter, sugars, vanilla, and mashed banana until smooth.
Pour wet ingredients into dry ingredients and gently mix until just combined. Do not overmix.
Fold in chopped pecans until evenly distributed.
Divide batter evenly between pans and smooth the tops. Tap lightly to remove air bubbles.
Bake for 25–30 minutes, or until lightly golden and a toothpick inserted in the center comes out clean.
Cool in pans for 10–15 minutes, then transfer to a wire rack to cool completely.
