Probably tomatoes, peppers, cucumbers to start

Of the three, tomatoes are probably the least suited to containers. While they're easy to grow in a container, the fruit you get isn't anywhere near as flavorful as a tomato planted in the ground.

A tomato plant can have roots which will extend 7-8 feet down. As has been mentioned, this can lead to a rootbound plant in all but the biggest containers.

Tomato flavor is generally best when you stress the plant a little in terms of water. Tomatoes can be treated a little like wine grapes. Once they set fruit you can either stop or severely limit irrigation. This makes the plant strive for its own water source and generally produces a more flavorful tomato (though with less overall production).

Too much water can produce a somewhat mealy tomato. Romas in particular are bad candidates for a container. If you're dead set on going the container route I'd recommend the smaller varieties (like cherry tomatoes). Something like a Sweet 100 or yellow pear do reasonably well in a container if you're mindful about your watering. If I remember correctly, indeterminates do a little better than determinates when containerized.

Both cucumbers and peppers are excellent candidates for container gardening.

As long as you're at it, you may as well add some herbs to the container garden. Herbs are very well suited to containers and can be an attractive garden feature as well.
