Clockwise from top left:
-- Yellow (Golden Delicious) apple;
-- Yellow corn muffin;
-- Yellow pepper; yellow squash, steamed.
And the milk is in a yellow container this time.
Other Y ideas: yams (read the label if you buy canned ones, though); (yellow) pineapple; a yo-yo.
For my husband:
-- Soy dog sautéed with yellow pepper and onion;
-- Corn muffin;
-- Steamed yellow squash with black pepper.
Careful: the default vote is only a 5 out of 10.
