Snacking is my big thing too! Honestly, if I let myself, I'd just snack all day...
However, I can enjoy some really healthy -- and tasty snacks throughout the day, in moderation of course.
Here's some (SCD legal) suggestions...
Fruit - favorites: apples, grapes, or frozen blueberries
Nuts - favorites: almonds or pecans.
Cheese - favorites: extra sharp cheddar, provolone, or if I'm feeling gourmet, bit of pecorino.
Veggies - favorites: celery, carrots, pickles, or olives.
A slice of proscuitto.
Half of a Larabar - favorite: cherry pie.
Hope these were helpful! Happy snacking!
