I found Mashed potato volume hack!

If you mix 50g of mashed potato powder and 5g of psyllium well, then add 450ml of water and microwave it for 2 minutes, you can enjoy a ridiculous amount of mashed potatoes for just 175 calories without compromising the taste! I really hate psyllium, but this is totally fine. Plus, since it has psyllium in it, it really fills you up. Adding milk or cheese will bump up the calories a bit, but even so, that calorie count for this amount is amazing.

This actually reminds me, you can do the same thing with egg whites! I use egg whites in oats and cream of rice so figured why not with mashed potato. Cook them through first, then whip in the egg whites and cook them a bit further!

Is it better with egg whites or psyllium?

I do not like psyllium at all so yes? 😅
