I like to use a bit of my own blend with half to stretch out the box. But in your case just use the whole box. I like to cut the bars into small pieces then smoosh the rest into a powdery kind of texture so that the flour incorporates much easier and smoother into the pot. I also just remove meat from the dish.

Bonus: add a bit of Worcestershire sauce and a teaspoon of honey.

Worcestershire sauce

I’m not sure if you’re removing the meat because you’re a vegetarian but if so, you should be aware that Worcestershire sauce is made with anchovies.
