Wow...this is easy!
Kind Bars or some sort of really good trail mix! You get your healthy fats from the nuts.....plenty of protein, vitamins and minerals. Then, you can get your sweet on with some dried fruit, coconut chips, etc......
I am not eating Kind Bars now, but they are incredible. I can't recommend them enough. Also, some of the Kind Bars only have 5 grams of sugar...and they are not processed in any way. They are gluten and sugar free (they use a touch of honey to sweeten the low-sugar ones).
Some of my favorite Kind Bars are the Salted Caramel and Dark Chocolate Nut, Maple Glazed Pecan and Sea Salt.
One thing I like about Kind Bars too is that I never had one where the nuts had gone bad and were rancid. That's pretty rare...nuts go rancid pretty quick. That means they always seem to be very fresh. I liked the grain Kind Bars too, in particular the Maple Pumpkin .
But I like the nut Kind Bars much more because they
REALLY fill you up and satiate, and are delicious but low carb, low sugar. They had become my favorite snack before my diagnosis.
