Housekeeper for one day a week that can make a salad

We have a couple up in Laurel Canyon on Lookout Mountain. They are looking for someone one day a week- cleaning, laundry and some windows.
They also would love it if before you leave for the day you can leave a salad for the couple to have for dinner. Nothing fancy but the husband loves cole slaw or tuna salad or a healthy vegetable salad to leave in the fridge. $25 per hour cash.
