Might have been discussed before.
Sold at aldi. 6.9g carb per serving (50g) normal spaghetti is 72g per 100g serving, so quite a difference.
I tried it a few weeks ago and tested bg's before and after with good results.
Only criticism is, this spaghetti substitute clumps together and doesn't flow freely like ' proper ' spaghetti.
Taste and texture is ok, a cross between Chinese noodles and spaghetti!
Aldi also do a black bean spaghetti which looks like pasta in squid ink......
Same carb content.
