Julie and I suggest you can place these side by side on a platter, but we rather like having a toothpick and putting the combo together on it (like the watermelon above).
And, these lend themselves perfectly for bruscetta. Drizzle olive oil on some sliced french bread, toast it in the oven, and put these adopt them! Consider adding things like fresh rosemary, mint, carmelized onions, roasted tomatoes....
fig jam meets the saltiness of bleu cheese and tartness of granny smith apples
pears like to be seen with salty cheeses like feta
grapes are best companions with aged white cheddar
pineapple is fantastic with parmesan - try a shaved bit of it atop the pineapple
strawberries and brie are good buddies
kiwi snuggles up nicely to goat cheese
peaches and mozzarella are best buddies
gorgonzola and plums might be companions because the stinkier the cheese, the sweeter the fruit that goes with it.
Remember to consider fresh herbs for many of these combos from thyme to dill, rosemary to cilantro. Also, pair them with a wine that adds the magic. Sangria is loved by all, but there are some great white wines for this - Chardonnay, Rieseling, and Gewürztraminer
