Recommendations on what veg to plant

I am going to restart a garden in the field again this year, to start off I will be putting some compost down then cover with cardboard and plant some rhubarb, this will free up a couple of large containers which I will use one for courgettes, still thinking on the other, but I recon rhubarb should be OK to grow in an open field as I doubt anything will touch it, but can you recommend any veg that I could grow in an unprotected area, which is open to deer, rabbits etc.
