Roast chicken thighs - portuguese style

I cooked this for lunch today and it's soooo easy and delicious we had to repeat. As with most of the posts in this blog, the pic is not mine, I found it on google images, but mine looked just like it. Besides, most times there is no time to take pictures because we just devour it all...And I'm not that good in decorating anyway. There are much more talented people around.

4-6 garden variety potatoes, peeled and in quarters
2 tomatos, in quarters
1/2 lime, divided in 4 pieces (or 1 lime in quarters)
6 garlics WITH their skins (but you can mash them with your hands a bit)
olive oil
rock salt
4-6 chicken thighs (but I used drumsticks too and it's also good)
black olives

Spread the potatoes in an oven proof tray (better if it's a pretty one, for it can be served just like that when done) and do the same to the tomatos. Put each piece of lime in the corners of the tray and spread the garlic around too. Place the chicken pieces in the tray, in a very spread fashion, so that you have chicken...potatoes...chicken...potatoes.
Give it all a good wash with olive oil (remember, portuguese style - the more, the merrier) some pepper if you want and spread rock salt on top of it all.
Roast it all in 180-190 degrees for 40 minutes. Remove it and spread the olives on top of it (I use a handfull and give it another drizzle of olive oil). Roast for another 10-15 minutes.

Serve with some salad
