Its about cost, plain and simple. Notice that when the trans fat laws went through, the schools were exempt. These school districts are feeding these kids 2 out of 3 meals a day and down here in University Place ( an affluent community) 35% of the students are on free or reduced fee lunch. The schools want to keep the cost of food as low as possible and ditching pizza in favor of healthier choices drives the price of meals up. BTW, down here pizza isn't only for lunch, they serve it the next day for breakfast too. Right along side the sausage and french toast.
