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 a noun phrase. You chose vegetables steamed with no oil or seasoning, which is a noun followed by a participle phrase. Before you continue, review the rules for parallel structure.
