I am the one who heads up the Semi Annual boardwide Veggie Challenge, and I can tell you this - YES, it is quite possible to get 12g of net carbs from Induction level veggies. Don't limit yourself to greens and lettuce.
For example:
1 cup of jicama (Salad veggie) = 5g net carbs
1 cup of red bellpepper, raw, cut into strips (Salad veggie) = 6g net carbs
1/2 can of pumpkin/which is .88cups (Other veggie) = 7g net carbs
TOTAL: 18g net veggie carbs
