Yes, another kitchen gadget! 
 
  Roaster ovens are similar to crockpot/slow cookers except
 
  they have an oven's temperature setting controls. 
 
  These usually cook foods in less amounts of time than you 
 
  would need if you used your stove/range's oven.
 
  You can make food in larger amounts, can keep foods warm for
  
  quite a while AND some people have these on hand just for 
  
  those large get togethers when you need more oven space.
