This is a quick, easy one-pan dish that takes minutes to prep and cook. I made this in a grab-what-you've-got-and-cook-it moment and it was an unexpected hit. I was rather surprised at how it turned out. The sardines are more savory than fishy and go well with this combination of veggies. Putting the oil, seasonings, and vegetables together in a gallon zip lock baggie and tumbling to coat the vegetables distributes the flavor more evenly from the start and the dish requires less stirring in the pan to mix. I use tomato paste that comes in a tube to cut down on waste.
