Healthy Rhubarb, Whole Wheat and Oatmeal Muffins

(My daughter made these the other day and they were really delicious)
2 cups chopped, fresh or frozen rhubarb
1 egg
1 cup milk
1 tsp. lemon juice
1/2 cup vegetable oil

2 1/2 whole wheat flour
2 cups brown sugar
1 cup rolled oats
1/2 tsp. cinnamon
1 tsp. baking soda
1/4 salt
Directions
In a bowl, whisk together the egg, milk, lemon juice and the vegetable oil.
In another, large bowl, with a fork, mix together the whole wheat flour, brown sugar, rolled oats, cinnamon, baking soda and salt.
Make a “well” in the center of the dry ingredients, and pour the egg mixture in, and stir just until combined.
Gently stir in the chopped rhubarb.
Spoon the batter into muffin cups or paper lined muffin cups.
Bake in center of oven at 350° F or about 28 – 32 minutes, or until a toothpick inserted in the center comes out clean.
Cool muffins in the pan for about 5 minutes, and then remove to a cooling rack.
Makes about 12 – 15 muffins (I made 15:)
