Several varieties of frozen DiGiorno pizza, Lean Cuisine dinners, and Stouffer's lasagna were recalled Thursday for potentially containing pieces of glass.

Nestlé, the parent company of the brands, announced the voluntary recall of 12 varieties of its products. The recall only affects meals with specific product codes.

The company said in a statement that no one has reported being injured, though "several" customers had reported finding glass.

"We are recalling these products because they may contain small pieces of glass that may cause injury," the company said. "Although our investigation is ongoing, we believe the source of the glass is spinach that was an ingredient common to the products subject to this recall."

*DiGiorno Thin & Crispy Spinach and Garlic Pizza
