Here are two of my favorite healthy subs for sweet and salty cravings:
cold and sweet craving:
frozen banana: freeze ripe, peeled bananas (great way to use the over-ripe stragglers) in foil and eat like a popsicle. so delicious.
crunchy salty craving:
Kale chips: pre-heat oven to 350, wash and tear kale leaves, spray with olive oil, sprinkle with salt (other options lime, sesame seeds, red pepper flakes, soy sauce) and bake for about 10 minutes, tossing half way through. Watch carefully as they go from perfect to burnt pretty quickly. So good and crunchy!!
