Lightly grease a clear glass loaf dish with nonstick spray or a thin swipe of neutral oil, then wipe out any excess with a paper towel. This helps the frozen salad release easily while still letting you see the creamy swirls through the glass.
In a medium mixing bowl, whisk together the instant chocolate pudding mix and cold milk for about 1–2 minutes, until smooth and slightly thickened. The mixture should be glossy and just starting to set.
Fold in the thawed whipped topping with a spatula. Gently turn the mixture over on itself until no streaks of plain whipped topping remain. The mixture will be light, fluffy, and pale chocolate in color.
Add the vanilla extract and a small pinch of salt, if using, and fold again to combine. The salt helps cut the sweetness just a bit, the way Grandma Jo liked it.
Roughly chop the slightly thawed frozen strawberries if they are large, so you get bite-size pieces in every spoonful. The berries should still be mostly frozen but easy to cut.
Fold the frozen strawberries into the chocolate mixture. Work gently so you keep as much air in the dessert as possible. You’ll see pretty pink streaks and swirls forming as the berries chill the pudding mixture.
Spoon the mixture into the prepared clear glass loaf dish, smoothing the top with the back of a spoon or spatula. Use the spoon to create soft peaks and swirls on top so they freeze into a pretty, textured surface.
Cover the loaf dish tightly with plastic wrap or foil. Place it flat in the freezer and freeze for at least 4 hours, or until firm around the edges and mostly set in the center. For a firmer sliceable dessert, freeze overnight.
When ready to serve, remove the dish from the freezer and let it sit on the counter for 5–10 minutes to soften slightly. Scoop into bowls for a softer, frosty salad, or use a knife to cut slices if it’s very firm. Serve cold, straight from the glass dish so everyone can admire the creamy pink-brown swirls and frosty edges.
