A US woman has sparked a debate after sharing a picture of her daughter’s lunch box.

Taking to the popular Facebook group “What’s in your lunch box?” a page dedicated to school lunch boxes, the mom posted a snap of the box, which contained strawberries, a mini bagel, a Babybel cheese, goldfish crackers and Reese’s chocolate.

But there was one particular section of the lunch box that caused a stir — the one filled with frozen peas.

“My daughter’s lunch for tomorrow!” she wrote. 

“Mini bagels were just coming out of the oven when I went to the store this morning – couldn’t resist!”

“Great for sandwiches or with cream cheese.”

But some parents were fixated on the section with the frozen peas.

“Are those really frozen peas?” one mom asked.

Another user asked if the peas were still frozen by the time her daughter ate them.

“My daughter says they are half thawed [when she eats them], which she loves,” the mom said. 

“We also put a cold pack with her lunch.” 

Other parents praised the mom for getting her child to eat the vegetable.

“That’s really cool,” one person wrote.

“My children eat vegetables, but never peas!”

Another user said their child also likes frozen peas.

“My kids love peas frozen or thawed!” they wrote. 

“I buy the organic frozen peas from Aldi. Cheap and delicious”
