Gather all ingredients: diced strawberries, ripe mango, avocado, jalapeño, red onion, cilantro, lime, and salt. Chop strawberries and mango into half-inch pieces, and dice the avocado into similar-sized chunks.

In a medium mixing bowl, combine diced strawberries, mango, and avocado. Add jalapeño and red onion, gently folding ingredients together without mashing the avocado.

Squeeze juice of one small lime over the mixture, adding a pinch of salt to taste. Fold ingredients once more to combine.

Taste the salsa and adjust with extra salt or lime juice as desired.

Transfer the salsa to a serving bowl and enjoy with multigrain pita chips or atop grilled chicken or fish.
