Cut the onion, into small pieces. Wash and boil the potatoes, carrot and beetroot. Corn kernels too need to be cooked. If using frozen ones, thaw them.
Peel the skin and mash the potato. Grate carrot and beetroot. Grate the cheese.
Put all the veggies in a bowl. Add the grated cheese to it. Put all the spice powders and mix it.
Make a paste of rice flour and water.
Take a ball of the mixture, dip it in the rice flour paste and then roll in semolina.
Heat oil in a pan.
Slowly add the semolina coated ball into it. Put three croquettes at a time.
Deep fry on medium flame until done. Remove on an absorbent paper.
Veg cheese croquettes are ready to serve. You can serve it with a dip or tomato ketchup.
