Another gluten-free find at Wal-Mart: DeBoles gluten-free rice pasta. I found it next to the regular pasta. There was spaghetti-style and penne. Both boxes were 8 oz and cost $1.47.
It tasted pretty good. I cooked it slightly al dente and it tasted a little raw and starchy. But when it's covered with Newman's Own Marinara sauce...yummy!
DeBoles also makes pasta from corn flour. I'd love to try that. I've tried corn pasta before and it tastes more like regular pasta than rice pasta does.
