Hi YL,
U can try other seasoning like yoghurt, ginger, garlic and seasame oil. Can use the remaining marinade and juices from the grilling to make into gravy for the cutlet. Just add some slice button mushrooms and corn starch to thicken the gravy.
As for a potato dish, u may try to make rosti, mashed potato or smashed potato. For rosti, cut raw potato into strips. Put some oil (may add some butter too) into a non stick frying pan, add enough potato strip to cover the whole pan. Use a frying slice to flatten the potato to obtain a potato pan cake. Add some salt and pepper for taste. U may add cheese, bacon, ham, onion for variety. Once brown, turn over and fry on the other side til brown.
For mashed potato, that's easy. Boil potato in their skin til soft. Remove skin and mashed them up with milk, butter and salt.
For smashed potato, get those small cute potatoes. Scrub them clean. Mix them with salt and olive oil and bake till cook. Grab a bunch of basil, chopped them up. Plus some chopped garlic. Put the cooked potato into a bowl, smashed them up coarsely with a fork tog wif the basil n garlic. Add salt n pepper to taste. Mix well.
