Preheat oven to 350 degrees F. Either lightly grease or paper-line the muffin cups or tins.
In a large bowl, combine flour, sugar, baking soda, cinnamon, and salt; set aside.
In a separate bowl, combine egg, vegetable oil, milk, lemon juice, and vanilla extract, mixing well. Stir the egg mixture into the flour mixture until just moistened. Fold in the shredded zucchini, chocolate chips, and pecans.
Fill the prepared muffin cups or tins 2/3's full. Sprinkle mini cinnamon chips on top of each muffin.
Bake approximately 20 to 25 minutes or until a toothpick inserted into the center comes out clean. Cool for at least 20 minutes before removing muffins from their liners.
Yields about 1 dozen muffins (depending on the size of your muffin tins).
