"To die for" is an idiom commonly used to describe something that is exceptionally good or desirable. However, if you're trying to vary your vocabulary, there are several alternative expressions you could use. One option is "heavenly," which connotes something divine or sublime. Another possibility is "mouthwatering," implying an intense desire to consume. You could also use "irresistible," conveying the idea that it's impossible to resist. "Exceptional," "enviable," and "covetable" are other words that could work in this context. Ultimately, the most important thing is to use words that accurately convey your meaning while also making your writing or speech more engaging and memorable.
