I will be visiting my grandparents that are in their 80's this weekend. I asked them what they would like for dinner and the response was .."maybe a nice roast with potatoes, carrots, celery and onions - something you can just throw in the crockpot". Sounds delicious, right? But I never have any luck with a slow cooker - the veggies just always seem mushy - and i never know what kind of meat to buy. And how do I make a "gravy" for the meat and potatoes? Any advice would be appreciated. Or ideas for other "hearty" NOT gourmet meals that would be well balanced would be appreciated. I thought about making a big pot of beef vegetable soup too.
