I made my own protein drinks. Either EAS Lean 15 or Pure Protein Whey Protein. Mix with bananas, frozen blueberries, unsweetened almond milk, and ice. I usually buy protein powder at Target, sometimes Walmart.
As for bars, Pure Protein are pretty good. Balance Bars are OK. Nature Valley now makes a protein bar they sell at the local super market (Metro Market/Pick and Save). Target usually has decent prices on protein bars.
