In a bowl, mash avocados with a potato masher or a fork until coarsely mashed.

Add the shallot, jalapeno, lime zest and juice (about 2 tablespoons), chopped cilantro, and strawberries, and fold until incorporated. Season to taste with salt. Serve immediately, sprinkled with additional chopped strawberries for garnish, or cover with plastic wrap pressed directly onto the surface and refrigerate for up to 4 hours or until ready to serve.
