This is our working recipe at the moment.
1 cup Stonyfield farm whole milk yogurt (has 3g fiber)
half package of soft tofu (protein, iron, and completely undetectable)
1 or 2 tbsp wheat germ (fiber & iron, but can be bitter in large amounts)
1 or 2 bananas (2 makes it sweeter)
mess of berries from the freezer (Costco!)
in emergencies: half and half or ice cream ad libitum
If I have a slice of lemon or lime around, i'll squeeze it in to brighten up the berries.
This is a work in progress. Ideas and suggestions will be keenly scrutinized.
Also: does anyone have a recipe for a smoothie that involves peanut butter? We are huge fans of peanut butter and unsure how to make edible smoothies out of it.
Update -- faster:
Cup of plain yogurt (I've started making it myself -- it's really easy!)
A good, trusted egg (or two)
A heaping cereal bowl full of frozen berries, microwaved for 60-90 seconds
