Wanting to bring in lunch meat and some frozen vegetables

Last year went to Jamaica and did air bnb . We didn’t realize how pricey potatoes are , so this year wanting to bring some frozen potatoes like hashbrowns and vegetables. And some lunch meat like pepperoni sticks . Last year went declared food but it was like snack stuff they didn’t check . Just wondering how much they do check ? will still claim though , I’ve heard other people brought meals from home and no issues . How hard are they ?
