Here is the way I prepared them: I sliced them in half, added some basil leaves and whole garlic cloves, tossed them in a little olive oil (a tablespoon or two for a cookie sheet full) and slow roasted/dried them in the oven at 250 degrees until they were wrinkly and somewhat dry. It took 4-6 hours. Afterwards, I packed the tomato halves, garlic and basil in a jar and added olive oil until they were covered (running a knife around the outside to be sure the air was out). Store them in the refrigerator. They will last for several months, but you will probably have devoured them before then.
We tried some over pasta with grated parmesan on top. Delicious!!! They would also be good on French bread or atop cream cheese as a dip.
I will never turn down an offer of cherry tomatoes again--gardeners always seem to have a surplus towards the end of summer.
Ready for the oven!
