A meal which has contains herbs than spices.
Having a joint (but not beef or pork) whilst on a lunchbreak.
Right, the bosses are away, anyone fancy a dutch lunch?
"You look like you've just seen a ghost".
"Nah. I've just had a dutch lunch".
Drinking beer for lunch. Actually very nutricious, considering that a good beer is similar to a sandwich in it's nutritional profile. Loaded with complex carbohydrates and vitamins such as B complex.
I met with Willem today for a Dutch lunch at the pub this afternoon.
