DID YOU HAVE A "STRONG" BREAKFAST?
I think most native English speakers would understand if you said "strong" breakfast but there is definitely a Spanglish element to this sentence. The idea of a "strong" breakfast/lunch is quite common and usually expressed in Spanish by saying: "Un desayuno fuerte".
The problem here is that "strong" is not the ideal word to use in this context. A more appropriate word would be "heavy" or "big" or even "filling". So, for example: "This morning I had a very filling breakfast".
If you really want to use the word "strong" it is much more commonly used to describe a tea/coffee: "I had a strong coffee this morning to wake myself up.
Hope that helps!
