The type of plants we are talking about for a kitchen garden will be any fruit, vegetable herb of spice.

I suggest a few salad plants so lettuces and radishes maybe have a go at some outdoor tomatoes!
You could try your hand at some cabbages too.
Herbs, go crazy! I highly suggest planting basil with and around the tomatoes as it helps to repel some pests.
But to be honest you can grow anything let nothing restrict your creativity.
