Spread the sauce on the hot pizza crust, sprinkle on the toppings, then put under the broiler for two minutes, until bubbling. If you want a few more mixing/cooking details, see this other post.
Since I'd only used part of the can of pineapple and also had some coconut milk in the fridge, I made Pina Colada:
1 (20 oz.) can of pineapple (or almost a can, in this case)
1/2 cup coconut milk (or use 2-3 Tbsp. shredded coconut and 1/3 c. water)
Half a tray of ice cubes or one handful
1 Tbsp. mild molasses
1 drop lime essential oil or 1/4 tsp. lime zest (optional but adds just the right touch)
Combine in a blender; turn on high until smooth. Add a little sugar or honey if it's not sweet enough.
I didn't use any more sugar; the lime boosted the flavor enough that the drink didn't really need anything else.
To the pizza and drink, add a salad or other vegetable, and there's supper!
