Where to buy good rolled oats?

Hello all.

First of all, I would like to apologize for writing in English. I recently moved to Netherlands so I don't speak Dutch yet.

I am looking for a place where to buy rolled oats. I have checked all the biggest supermarkets (Jumbo, AH, Lidl) but I haven't found what I need.

The oats they are selling are extremely minced and they taste like some sort of powder, what I don't like.

The only thing I eat for breakfast is oatmeal that is cooked from rolled oats.

Can it be found in any of the supermarkets? I haven't seen them yet. Maybe there is another shop that specialized in foods like this? I would be grateful for any kind of help.

Exactly like these:


Thank you in advance.

P.S. I live near Delft, Den Haag, Rotterdam, so any shop in that area would be great.
