Massive "shrimp cake" for under 300 cal!

I invented this one about a month ago and my wife has made me make them about six times since. If you are looking for a huge portion of food at little calorie expense, read on! The following makes two large cakes.

Ingredients:
1 lb potatoes - peeled (white or Yukon work better than red or russet)
1 egg white (or 3 tbsp of egg white from a carton)
Roughly 6oz shrimp... Peeled and cooked (boiled is best, cut up if they are bigger than 50ct)
1 red pepper
1 tbsp mayo
Salt, pepper, dill, garlic powder, any Cajun-Caribbean-seafood-chicken style seasoning you like.
Powdered butter flavor for popcorn is a good bonus, but not necessary

Directions:
Boil the potatoes for 45 minute to an hour, until they can be mashed with ease.
Mash the potatoes in a bowl, season with salt, pepper, garlic powder, your seasoning of choice, and the butter powder.
Add the egg white
Blend or process the red pepper.
Pour HALF into the potato bowl and half into a small bowl (for sauce later)
Mix the potato bowl until pretty smooth, then add the shrimp

Have a 6-9" non stick pan going at medium to high heat and sprayed with PAM or other equivalent
Spoon half your potato-shrimp mixture into the pan and spread your cake evenly.
I find it easy to have two pans going, because after roughly 5-7 minutes, you are going to flip it, and it's much easier to put one pan over the other and flip the whole thing. Otherwise it gets messy.
Cook the other side for the same 5-7 mins and slide onto a plate. Repeat for your second cake.

Mix mayo in with the leftover pepper purée and add some salt and dill. Spoon or pour over your cake.

The cake comes in at roughly 275 calories and the sauce at 75 calories per serving. These will be huge, filling, and delicious if done right. I will post a pic the next time I make em.
