Exactly what I found, it's interesting stuff.
Sadly because of the current prices I can't use them to replace any of my meals as a protein source.
It's £6.50 for 12 grams of insect protein so not even a meals worth. Whereas I can get 80g protein, 3-4 meals worth, in 100% grass fed ground beef for only £4.60 so no comparison at the moment.
