Now that's one I haven't tried, but I'll give it a go.

Hubby hates cucumber and anything related, like gherkins & dill pickles, but for some reason he will eat tzatziki dip, maybe because the cucumber is grated and drained and it is in yoghurt, so the chances of him touching PB & dill pickle even with a 10 foot pole is nil, zero, nada, zip.
