Take a look at the sentence again:
We hate having dinner at Aunt Ida's house because she is a vegan health
nut. Baked tofu, __________, and decaffeinated tea do not make a satisfying
meal!
The blank requires an noun phrase. You chose vegetables that are flavorless, which is a noun followed by an adjective clause. Before you continue, review the rules for parallel structure.
