Food for thought

My source was Analytical Grammar on Facebook.  Comments added more food-related idioms that could have been put into that fridge:

• good gravy
• two peas in a pod
• humble pie
• chopped liver
• big cheese
• apple of her eye
• in a pickle
• bun in the oven
• cup of tea
• sour grapes
• cutie pie
• cool beans
• cold turkey
• bad eggs
• whole hog
• food for thought
• a grain of salt
• salt of the earth

What else could we add to this list, wordsmiths?
