>>21398374 (OP)sweat sliced garlic, anchovies, and red onions in a good amount of olive oil till the anchovies dissolve and garlic is slightly browned, as well as a small pinch oregano and chili flake, add in your tomato(either sauce or crushed canned plum tomatoes, depending on texture preference), reduce it slightly, add kalamata olives and capers plus pasta water, add spaghetti when its slightly undercooked, finish cooking in sauce, toss or stir well till the sauce thickens slightly
plate it, finish with breadcrumbs and chopped parsley, wa la
you can also add sundried tomatoes for some more tomato flavor or a can of good tuna if you want more protein/fish forward
its a very easy dish, hard to fuck up tbqh
