I love mine too much! Lamb especially...
What's your favourite?

Lamb???? Oh my god!!! I lamb!!

I don't have a favourite Sunday roast. I'm Dutch, we don't do Sunday roasts...
But if so, lamb would definitely be my favourite!

Actually yours is the best.. by far. So what time do you want me to come over?

Roast beef and Yorkshire puddings.

Got to be a good roasting joint though.

Any roast will do for me.. With new potatoes, green beans, carrots....

left over from my upbringing and my married days
no matter how busy I get during the week
Sundays I usually try to set aside
as the day when mama cooks like she used to..

I sometimes put a chicken on the rotisserie
mash some potatoes
or pehaps make some biscuits
sometimes it might be a turkey breast
or pork roast or maybe potroast

AND... Now I'm hungry

I make braised lamb chops in apple cider that is just awesome.

As for roasts, I do a few different ones, mainly in a slow cooker but sometimes in the oven (depends on the dinner activities)
I've even done briskets in the grill/smoker.

I do Pork Long Roast
Basically, its a seasoned pork loin with potatoes cut into quarters length-wise. Carrots are cut in half then sliced length-wise and I use pearl onions for shape contrast.

I do a number of different beef cuts, Sirloin Tip being my favorite.

I also do a number of different chicken roasts.

Since I now only cook for myself, I do a lot of cornish hens.

Nearly all my life there has been some type of roast for Sunday dinner. Here's a page at Pinterest that gives recipies for different roasts.
