For Crepes whisk eggs with sugar, add flour and a pinch of salt. Mix well. Start adding milk gradually and keep whisking. Try to avoid lumps. Set aside for a couple of minutes. Meanwhile sauté chopped bell pepper and onion on some oil for several minutes (approx. 5-7). Start cooking Crepes, for the first one I use a table spoon of butter to cook on. I do assembling in parallel to cooking Crepes: on a Crepe a table spoon of ketchup goes. Distribute evenly, add some chopped ham, grated cheese, sautéed vegetables and sprinkle with herbs. Roll. You may reheat Crepe rolls before serving.
