I tried the egg, but it still needed moistening (or more than one egg). I also added butter, almond milk, sage and prodigious amounts of Asiago cheese. It was delicious but the cheese was not Whole 30 compliant and technically I should be starting over. However, I decided on day 1 that this would be a “dirty thirty”. Unfortunately I feel quite bloated this morning and it may be due to the cheese.
The egg goes in raw, but the heat of the potatoes cooks it. Not much riskier than a runny fried or scrambled egg. IMO anyway.
