Chop the veggies and greenery: carrot, onion and cilantro.
Blend the mix: boiled lentils, veggies and cilantro. It's ready when it's half blended (a half of lentils should stay not blended).
Put everything into a big cup/pan, add spices and soda, and mix it thoroughly.
Add gradually flour and lentils liquid. Keep mixing.
Once your mix is in a good condition, stop mixing and start create a sphere-like cutlets. Don't bother, if your cutlets are very sticky, it's a good sign.
Pre-heat the frying pan and wrap your cutlets with breadcrumbs. Flat them on your plate with breadcrumbs and put in the frying pan.
If you have unused breadcrumbs - put them on top of the cutlets in the frying pan.
