This neat Hamilton Beach Personal Creations Blender, it’s under $20, at Walmart. It comes with two travel jars & lids.
It’s simple and does the job for quick smoothies. This is compact and easy enough to bring along when traveling. Clean up is simple too.
I’ve been making fruit smoothies using frozen blueberries & mango, adding 2 t of Chia seeds, plain Greek yogurt and some Almond Milk. No need to add any sugar – the fruit is sufficient. I add 2 ice cubes and blend. Voila!
