In a pot cold water add the potatoes and let them boil for 20-30 min
Peel the carrots and cut them in quarters lengthwise. We are looking for almost bite size quartered carrots
Cut both endings of the green beans and wash them
Wash the salmon and pat it dry. We will be keeping the skin so if you do not like the feel of scales, remove them. Note that I am picky here but on most of the cases, the skin can be cooked as it comes from the supermarket. Cut it in the portions that you want to serve it.
in a caserole add a bit of olive oil and spreadt it around
add the veggies and marinate them with salt and pepper. Mix them around and make sure to open a spot with a bed of green beans for the salmon fillets
Preheat the oven on 180-200 degrees celcius
At this point you have two choices. Either remove the potatoes (as they are not already cooked) and let them finish in the casserole OR let them finish boiling, cut them, and add them in the casserole in the last 10 min for a quick bake. I usually chose the latter as my casserole is a bit small
Cover the whole thing with aluminium foil and let it bake for 30-40 minutes.
At the 30 minute mark, uncover, increase the heat to 220, add the potatoes and let it be for 10-15 minutes or till the salmon is cooked and the carrots are at your preffered softness.
Serve them immeditelly and do not forget to add some of the juices on top
