I have a post somewhere with some other smoothie recipes.
My "decadent" smoothie (from Outdoor Magazine) is freakin' awesome:
2 tablespoons natural peanut butter
3 tablespoons unsweetened cocoa
1 cup fat free milk
3/4 cup ice
1 tablespoon honey
2 tablespoons ground flaxseed
2 tablespoons ground wheat germ
Makes two servings. 402 calories, 49 grams carbs, 18 grams protein, 19 grams fat, 14 grams fiber
I don't have the above one very often because its a little large on the fat (42%) but those 14 grams of fiber will get you shitting in no time.
This is a pretty badass one I've been making lately as well and use every now and then after a hard workout:
2 cups blackberries
1 cup plain fat-free yogurt
1 cup apple juice
1/4 cup honey
1 large banana
CALORIES 265(3% from fat); FAT 0.8g (sat 0.2g,mono 0.1g,poly 0.2g); PROTEIN 5.7g; CHOLESTEROL 2mg; CALCIUM 192mg; SODIUM 62mg; FIBER 8.7g; IRON 1.2mg; CARBOHYDRATE 63.2g
I've been putting a scoop of Whey (vanilla) every now and then which is pretty good as well.
