One of my Portuguese guilty pleasures, along with (ethically questionable, I know) octopus salad. Highly recommend trying this if you can get your hands on some fresh sardines.
Edit: grilled sardines are also a Japanese thing, so you might have luck finding them at an Asian market if your fishmonger doesn't have them.

Though I can't prove it, I'm edging toward the belief they share resources with each other, including water and nutrients through the root system.
All these facts and ideas are easily undone by particularly defining "awareness" and so this is largely a terminological problem.
The discussion quickly becomes, "Define awareness." or ... more generally ... "Define consciousness," which we see with machines, insects, plants, even single celled organisms.
Here's what science does tell us repeatedly: Those things which humans as a species are convinced have no consciousness is decreasing. Most, even today, would not believe an octopus is conscious, but we now think they are. Dolphins. Birds, even fish now have scientific studies indicating they are self-aware.
So, yeah, justifying the eating of plants because they lack self-awareness isn't a valid argument in my book.
That doesn't absolve us of a mission to reduce suffering for the things we eat.
Plants can certainly suffer and it's trivial to identify.
I believe the dog is happy and excited and eager to greet its friend of another species, but many, many people believe that dog is exhibiting purely mechanical behavior driven by instinct alone.
As usual when we apply "random ideology" we fall in an end road. From this point all are exceptions and excuses to fill the plot-holes, so the new guardians of the moral can keep asking for donations
You can also made them in the oven wrapped in aluminium paper if you don't have a proper grill.

The secret is, don't buy cheap ones. Look for brisling or any other small fish packed in olive oil. $3-5/can is a good sweet spot, although you can pay $9 for a can of imported Portuguese sardines no problem.
Speaking of Portugal, they do grilled fresh sardines. My 3 year old insisted on eating them daily when we were in Lisbon
