The intervention was positively associated with the percentage of meals purchased with vegetables: baseline vs. intervention (60{\%} vs. 64{\%} of meals purchased with vegetables; p < 0.01); intervention vs. post-intervention (64{\%} vs. 67{\%} of meals purchased with vegetables; p < 0.01); and baseline vs. post-intervention (60{\%} vs. 67{\%} of meals purchased with vegetables; p < 0.001).
