The test items were sampled by the folks over at E!, who visited the company headquarters back in February. Here's some of the more interesting items they saw:
- Meatball Thickburger - Carl's Jr. (and Hardee's) have a long history of putting meat on meat, so it's not a surprise that one of the things they tested is meatballs on a beef patty along with what looks to be mozzarella and marinara between two slices of toasted bread.
Also spotted were the Bisnut (which actually made it to restaurants for testing back in 2014), Pizza Fries, and a Birthday Shake.
To my knowledge, only the Bisnut and the Pizza Fries have ever been spotted in the wild (i.e. in actual restaurants).
