and drain'em
while waiting for the water to boil, you can start with the white sauce, simply melt butter, add flour, whisking to avoid it from curdling, followed by milk and chicken stock, stirring occasionally at all times till the sauce becomes thick
Actually, mean while, in between , before or after those two you can start making the filling. Mine, was a mixture of chicken , meatballs, fish fillet, crab meats and something which I didn't quite know what they were called which I found in the freezer and just threw them all in.,that is after sauteing the onion . when all the chickem etc are well cooked, add in thinly sliced potatoes and a dash of black pepper, abt 2 tsp, add in a little bit of water to soften the potatoes
Once all three main ingredients are ready, you just mix them all together
