I've seen five star recipes say things like "Hawaiian pizza - add pineapple, tuna fish, and lasagna". So, yeah, the star ratings are meaningless - but then there are too many recipes to sort the wheat from the chaff.
The target audience for this recipe is a Venn Diagram of "people who love lasagna but nobody else in their life does" and "people who can't eat ham for religious or dietary reasons" and "people who have no reverence whatsoever for pizza" (which also, according to some, is a superset of Hawaiian pizza eaters to begin with).
That's not a tiny number but it's not large either.
