For what it worth: nutritional yeast is great to replace parmigiana-like cheese. For mozzarella it’s probable a bad choice if you want to be as close as possible, but yeast is definitely not an hallucination as a cheese replacement. I’d be interested to see one or two propositions if you’re willing to share.

You ask for vegan recipes from a website. AI ignores actual content and instead offers "helpful" tip. This qualifies as hallucination. The system should help you access the web and instead it implies that the content is missing. This is actually why I prefer Edge over Chrome, they are similarly hostile to users but they are also utterly incompetent.

I agree about the nutritional yeast. Tastes great but has only a single texture that can't really stand in for most of cheese types. Apparently there was a recent breakthrough with E coli producing milk proteins that sounds very promising.
