Drain sardines and place them in a small bowl. If using bone-in, mash gently with a fork (the bones are soft and highly nutritious)
Add lemon juice, herbs, olive oil (if needed), and a pinch of sea salt
Stir gently to combine. Taste and adjust seasoning
Serve over a bed of greens, on top of cucumber slices, wrapped in lettuce, or with AIP-friendly flatbread or crackers
