1 can (10) refrigerated biscuits
1 c. milk
1 (6 1/2 oz.) can tuna
1 (10 oz.) can Cheddar cheese soup
2 tbsp. minced onion

Arrange unbaked biscuits in a greased 9 inch square pan (baking dish). Combine all other ingredients and pour on top of unbaked biscuits. Bake at 400 degrees for 25 to 30 minutes. (Biscuits will rise to the top and brown.) This may be doubled and baked in a 9 x 13 inch pan.
