You may want to skip the frozen food aisle on your next trip to the grocery store. Nestle USA is recalling several of its frozen products because of a "potential presence of foreign material."

And by "foreign material," Nestle means pieces of glass.

The recall covers nearly 3 million products, including several DiGiorno pizzas, Lean Cuisine meals and Stouffer's meals.

The common denominator in these dishes: spinach. As to how glass winds up in spinach -- that's beyond us.

The company said it's still investigating, and that so far, no injuries have been reported.

A full list of recalled products are on Nestle's website.

If you have one of the recalled items in your freezer, call the consumer services number or just toss it out.
