Strangely, I think we usually treat "beans" as countable. I would ask "How many beans to you usually have for lunch?" (Of course, I wouldn't actually be expecting a number for an answer.)Beans creo que es un sustantivo incontable. Entonces How much beans do you usually lunch/have for lunch?
Why strangely? Beans are clearly countable, as a matter of fact, the noun has both a singular and a plural form (the Collins and the Cambridge dictionaries list this noun solely as a countable noun), and does the noun in Spanish. I agree that asking about the exact number of beans that you eat/ate/have eaten is kind of weird, it would also sound strange in Spanish, but from a strict grammatical point of view, the question must be How many beans...?Strangely, I think we usually treat "beans" as countable.
Is it correct to say: How muchofbeans do you usually have for lunch?
If it’s not grammatically correct at all, is it correct to say: how many beans do you usually have for lunch?
Plus, would the answers “a few”,“a little”,
or “many”
be good answers?
In my variety of English I can't imagine saying 'a little' as the answer, even allowing for the fact that the question is rather strange.
How many beans do you usually have? A few. A lot. Not many.
