Too minimally processed-I’d say it’s Group 1. You’re taking Group 1 ingredients (avocado, jalapeño, lime, onion, maybe tomato and cilantro) and chopping, squeezing and pounding them. It can entirely be done with stone tools.
Salt is the Group 2 ingredient that I was mentioning. Nova calls out adding salt or sugar to Group 1 makes it Group 3, and specifically calls out Group 1 does not contain added salt.
"Minimally processed foods, that together with unprocessed foods make up NOVA group 1, are unprocessed foods altered by industrial processes such as removal of inedible or unwanted parts, drying, crushing, grinding, fractioning, roasting, boiling, pasteurization, refrigeration, freezing, placing in containers, vacuum packaging or non-alcoholic fermentation. None of these processes add salt, sugar, oils or fats, or other food substances to the original food." https://pmc.ncbi.nlm.nih.gov/articles/PMC10260459/
