They sell Joe's Tasty Travels at Walmart near the bulk section and I usually cruise by there to grab a bag of inexpensive snacks. Half a cup of these soya nuts contains 25 % of your daily iron intake with only 800 g of sodium which I find quite good for a salty little snack. I find by popping one or two at a time I can curb my snacking and satisfy my need for a good crunch. They're also a source of fibre.
