My first recipe is similar to yours - never tried the almond extract - but it sounds good! You can also add 1 Tbsp of wheat germ to any smoothie for added fiber, but the consistency is an aquired taste.
#1) Strawberry-Banana Smoothie
1 medium banana, 4-5 large strawberries, 1/2 cup vanilla yogurt (or any other flavor), 1/4 cup milk, 8 ice cubes. You can also add 1 tsp of honey, but I leave it out to save on calories.
#2) Banana-Mango Smoothie
1/2 medium banana, 1/2 - 1 mango cubed, 1/2 cup pineapple juice (or orange juice), 1 tsp lime juice, 8 ice cubes.
#3) Raspberry Lemonade Smoothie
1/2 cup lemonade, 1/2 cup lemon yogurt, 3/4 cup raspberries, 8 ice cubes
#4) Chocolate-Mocha Banana smoothie
1 medium banana, 1/2 cup coffee yogurt (or vanilla or chocolate mousse yogurt), 1/4 cup milk, 2 tbsp Ovaltine (or other choclate powder mix), 8 ice cubes.
Enjoy!
