I think the secret to growing food really well is not liking it.
Case in point: we grew wine cap mushrooms last year and did not like them at all. Now they are growing all over the place, spreading far beyond where they were planted. At least they look pretty.
The other thing is ground cherries. They look like tomatillos, little berries that grow in papery husks and are sweet. They're not bad, but they weren't our favorite. I think we had two or three plants on top of the terrace. Now we have ground cherry plants popping up EVERYWHERE. They're in all the garden beds and more. It's really quite amazing.
Maybe if we focus on not liking tomatoes our tomato plants will start growing!
