Farinaceous repast? (4)

I believe the answer is:

meal

I'm a little stuck... Click here to teach me more about this clue!

'repast?' is the definition.
(I know that repast can be written as meal)

I cannot understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for meal that I've seen before include "Eg, breakfast" , "Grain ground to powder" , "Lunch or dinner, say" , "Breakfast, lunch, supper" , "Food for male" .)

I've seen this clue in the Evening Standard.
