Here are some handy recipes that call for strawberries (or any berries, really) at the point of mushiness. Remember, you can always toss them in the blender and make a smoothie, like above.

1. If they're really mushy, mash them up until they're entirely pulpy and put them in an ice cube tray and freeze. You can use them later to cool AND flavor your drinks.
2. If they're still retaining some element of solidness, you can chop them into bits and put some honey on them. Let them sit a while, and then enjoy.
3. You can also cut them in half, sprinkle some sugar on them (real sugar, not artificial sweetener--this is important!), and then mash them just the tiniest bit with a fork, potato masher, etc. Let it sit for half an hour and you'll have some strawberry sauce for ice cream, angel food cake, etc. Freeze whatever you don't use to have for later.
4. If you want warmer sauce, you can cook them in a pan with a sweetener (honey, liqueur, juice, sugar).
