OK, so maybe "meal" is a bit of an exaggeration. Perhaps a "nosh" is more accurate. Alright, let's be honest here, in most cultures the combination of this:

and this:

is a snack.
But to the parents of the non-eaters of the world, a thin "schmear" of peanut butter on a Ritz cracker is in fact a meal. It clearly has a carbohydrate and some protein. And since peanuts are a subgroup of legumes and legumes are a subgroup of vegetables, then I think it is safe to say Eliza ate a vegetable tonight. Yes, the logic is a bit stretched, not unlike Reagan's effort to categorize ketchup as a vegetable (since some tomato had made some contribution to the ketchup).
Eliza has in the past scraped the peanut butter off of the Ritz and then licked the peanut butter off of her finger. But tonight, she at the Ritz with the peanut butter on it. The combination of these two things going in Eliza's mouth at the same time is what I think makes this Eliza's first meal.
Time to break out her baby milestone book and add a page.
P.S. please do not leave comments about the questionable nutritional value of a Ritz cracker. They will not be well received. :)
