This is a good, fast soup recipe! I used Yellowfin that I caught in Mexico last year and followed the recipe almost exactly (I estimated on vegetable amounts and tuna) and it came out very good. It could use more herbs and possibly some salt but overall a good recipe. I debated on 3 or 4 stars and gave this an extra star for the nutritional value, ease to make and good base to adjust for taste. I am curious how the flavor/texture may change to not mash the potatoes and will try it again with that idea. Thanks for a great, healthy soup!
