Vowelburger™ Bread-lover's Double Supreme

^{Inspired by Avi’s Vowelburger™ Riddle here.}

Vowelburgers™ has decided to start changing things up a bit for bread connoisseurs and they have started making the Bread-lover’s Double Supreme with two consonant buns on the top, two consonant buns on the bottom, and two vowel patties sandwiched in between. The patties are the same in every burger, but each burger will have a different combination of buns.

Here is their menu:

Can you identify each type from the description on the menu?
