In general, the use of technology to modify food plants to taste better is interesting to me, as it's a potential benefit to the consumer in comparison to benefits on the production side - farmers and agribusiness, including shippers and retail.
I agree that it seems like there are already lots of taste options to pick and choose from to assemble a healthy diet. I can't imagine someone with a Doritos habit switching to non-bitter mustard greens!
The coffee that @Mjx mentions is an interesting one though. If the caffeine was knocked out via CRISPR, it might well be possible to produce a much better tasting decaf coffee bean that didn't have to be processed with solvents or steam to remove the caffeine and there's clearly a market for decaf already.
Edited to add that allergen-free peanuts could be a good thing, too, though that's not a taste thing.
Here's an article on the CRISPR mustard greens, headed to restaurants now and perhaps coming to a store near us later this year! Pairwise Rolls Out First CRISPR-Edited Produce to U.S. Restaurants
