Qué vs Cuál

Question

When do you use qué and when Cuál?As per what I understood qué translates to what whereas Cuál translates to what or which. Then , in the starting line, why can't it be Cuál... as in "Which (food) do you like...?"

The question is actually saying "What do you like to eat in Summer?". In the lesson we are explaining that Qué can be followed by a verb, e.g.  "¿Qué te gusta..." meaning "what do you like...?, or  ¿Qué quieres hacer? meaning "What do you want to do? 
"Cuál would be OK if we had to make a choice, for example:

Tengo este vestido y esta falda.
I have this dress and this skirt.
¿Cuál te gusta más?
Which do you like the most?

Here it'd be OK to use cuál, as it is asking which - which one (out of those two choices)
I hope this clarified it.
