But onions are actually good for you! I’m not judging, I get the heebee-jeebees just thinking about goat cheese. What a great way to make onion dip. We love the stuff!

Hahaha, goat cheese scares me too! I have a number of food fears that I should deal with. 😛

I cannot believe you grew onions, then again, nothing surprises me with you. Absolutely amazed.
That dip is amazing my dear.
Suzanne says
As a child I too hated onions, would pick them off or refuse to eat anything they touched, the raw ones that is. Now I tolerate them raw but sliced very thinly and used sparingly but cooked, thats another story. Love that dip.

while there are many, many things to do with a plethora of onions, this is among the finest!
