Anything you'd use canned tomatoes for should taste just fine.
I like to make a simple red bean and rice side dish with tomatoes. It doesn't have a recipe, basically you saute a small onion and some chopped garlic to in a saucepan, add in a can or two of red beans and an equal amount of tomatoes and let simmer until hot, then toss with a couple of cups of cooked white or brown rice. Add Tabasco or your favorite hot sauce to perk up the flavor a bit. This is good with tacos, enchiladas and simple meat dishes.
Speaking of tacos, I always add chopped tomatoes to my taco meat (we use turkey) to add flavor and stretch the meat a bit. I'd add about a cup to the meat mixture. You may have to reduce the amount of water you add if you're using a taco mix since the tomatoes will be juicy.
Also, try chopping the tomatoes, giving a quick saute in olive oil to heat them up and then toss with cooked pasta, a bit of olive oil and grated parmesan cheese, pepper and oregano for a nice fresh sauce. It's a nice break from the usual marinara, and you can add in other veggies as well, we like broccoli (add to the pasta water a few minutes before the pasta is done to cook it) mushrooms (saute with the tomato), etc.
There's lots of stuff you can do with tomatoes. Enjoy!
