Thanks MC, I just threw it all in there....
Sorry I'm late with this one. With roasts, I put the onions in bottom under the roast. I only add a little broth; a good roast will be b juicy on its own. Then I stack veggies ON TOP of the roast, trying to keep them out of the broth. You have to salt them separately but they slow roast and are delicious wothout being mushy.
