Step 1

Preheat oven to 350 degrees and spray a 9 x 5 bread pan with non stick spray.

Step 2

Wrap grated zucchini in a paper towel and squeeze until some of the liquid releases.  You don't need to completely dry it out.  Just a tablespoon of liquid or so.

Step 3

In a large bowl, combine flour, baking powder, baking soda and salt.

Step 4

In a small bowl, combine milk and vinegar. The milk will curdle a bit.  (you just made homemade buttermilk!)  Mix in melted butter and egg.

Step 5

Add milk mixture to dry mixture being careful not to over mix.  (over mixing will make for a low rising bread).

Step 6

Add grated zucchini, cheese and onions.   Mixing lightly until just combined.

Step 7

Pour batter into prepared pan and bake at 350 degrees for one hour.

Step 8

If toothpick inserted comes out clean, bread is done!  Cool for 10 minutes in the pan.  Remove carefully and cool on wire rack.
