Flew MAD-LHR with Iberia on Friday.
Starter: Salad (decent portion)
Main: Steak (well cooked, still slightly pink), green beans and potatoes
Dessert: Do&Co chocolate moose

What really impressed me (I'm easily impressed): Iberia had a bread basket! An FA also came around after meal service with a bottle of whiskey and individually wrapped Guylian.

I used to make a point of avoiding Iberia on trips to Madrid pre-COVID but their food service is currently better than BA IMO. Apologies for no picture, I just wanted to post as a comparison.
