Pushes blessed old items of food (4,8)
I believe the answer is:
eggs benedict
'food' is the definition.
(eggs Benedict is a kind of food)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for eggs benedict that I've seen before include "something for breakfast?" , "Breakfast dish with hollandaise sauce" , "Dish with ham on toast" , "Dish served on toast" , "Dish topped with hollandaise sauce" .)
