I will add a splash of soy! It really needed a touch more saltiness. I love the idea of making them ahead and the economy of scale makes it work the prep time. A promising recipe that I can see lots of fun flexibility with. On the day you eat it...it will be easy enough to make the prep worth it.
Since this recipe involves a lot of chopping, I decided to spend the time to meal prep and make 8 individual servings. I didn't have jars, so I just used tupperware. I love the fresh ingredients in this recipe, but it tasted a little bland. Maybe it was the brand of miso paste that I had, or I added too much water.
When I was ready to eat the next one, I added a teaspoon of miso paste to what the recipe called for. (I didn't want to add too much more of the paste because I like to watch my salt intake.) I also added a lot less water, and it was much better! Adding the hot water didn't work out for me, so I just finished heating it in the microwave.
I tried this for an easy work lunch. It was FABULOUS. Easy to prepare and delicious. I didn't have jalapeno so I used red pepper flakes. Extra cilantro is great. Given the nature of the recipe, I think it works best for single servings and not for large quantities (unless you make multiple, single servings). I was not sure of the "hot water" step so I just added tap water and microwaved the entire container. Worked out very well.
Also, yeah, it doesn't take ten minutes, unless you have a sous chef (or a loving uncle?) to do all that chopping for you.
