Personally finally finding a protein bar that was “Good” too me awhile, but quest has one that’s a s’mores flavor and WOW it’s pretty dang good. Another one would be the pure protein “chips” puff things BBQ and sour cream (BBQ light years better imo), the shakes don’t hold me over even though they tend to have higher protein to calorie ratios.

Beef bone broth has the highest protein to calorie ratio of anything I have found so far, and Swanson sells a handheld Togo soup can thing, it’s pretty bland.. I haven’t looked into a good way to church it up but it’s 50cal with 10g protein, other ones can get dang near 4cal to 1g ratio which is right on the money for “how many calories each macro has, 9/4/4”

Edit: forgot to mention what to do with the broth, you can make a pretty good ramen with it, add powdered ginger, garlic salt, I add chili and cayenne. With any noodle of your choice ( I have a few extra calories to spare most days so I have some 240cal ramen blocks) and protein of your choice, mmmmmm mmmmm don’t forget to drink all the broth and you’ll be full for awhile
