This is a delicious main dish. The lemon flavor is subtle enough not to overpower the dish but strong enough for you to know it is there. After being converted from metric, the recipe calls for 12 1/2 oz of pasta. As per my box of shells, 2 oz is a serving. The amount of pasta was reduced to 8 oz and not having green beans, fresh asparagus was added the last 2 minutes. I did add some freshly ground salt and pepper to my serving.
The lemon zest and chile made the flavor in this tuna and pasta dish outstanding! This is a very fresh tasting dish, and I loved it! Will adapt some of my recipes, and will make this again! Thanks!
