You can blend them up and make your own soup or V-8 drink, snack on raw veggies. Cut up fruit and put them in your drinks, non-alcholoic sangria style--this will mke them tastier. Broil them and add them as garnishes on your meats. Stuff roasting chickens with oranges. Slice them up and put them on sandwiches or even hot dogs -- Chicago style! Did you know that Chicagoans practically put a whole salad on hot dogs? Cukes, tomatos, lettuce even. Cut fruit up into yogurt. Nuke them with cinnamon for a old fashioned cobbler taste.
I find that planning your meals can be very helpful when buying veggies, which, after all, are perishable. But if you know what you're eating ahead of time, you can work that understanding into your lunches and dinners.
