Lazy gardening is the best gardening of them all ;0)
You could mulch your garden: it stops weed and keeps your soil moist, so you don’t have to water that often.

You can grow veggies like crosne (Chinese artichoke). Simply plant a couple of tubers in a the biggest container you can find and then forget about it all together. It doesn’t need any special care. Go back to the container in late fall and you have hundreds of delicious crispy tubers you can harvest all winter. Best veggie for the lazy gardener. (You only have to water them in extremely dry times)

Use plastic bottles to set up an automates self-watering system - this will also save you a lot of work and time.
