A feast for the feast day

In celebration of St. Faustina and Bl. Francis Xavier Seelos, we had a very Polish/German dinner yesterday:  Polska kielbasa with roasted potatoes, carrots and onions.  I also made a chocolate peanut butter pie for dessert:

Roasted vegetables are one of my favorite fall and winter meals because they are so filling and hearty, but also because they are so quick to make!  It took me less than an hour, including all of the preparation:

1 medium onion, chopped into 1-2" pieces
3 carrots, chopped into 1" pieces
2 potatoes, chopped into 1" pieces
1 lb polska kielbasa, cut into 1" pieces
4 T olive oil
Rosemary
Sage
Marjoram
Black pepper

Preheat oven to 425 F.*  Put chopped vegetables into a large zip-top plastic bag.  Add olive oil and seasonings; seal bag and shake well, until all pieces of the vegetables are coated.  Pour vegetables out onto foil-lined baking sheet and add kielbasa.  Mix well.  Bake for 20 minutes.  Remove from oven and stir well; put back in oven to bake for another 20-25 minutes or until the vegetables are cooked through.


*Some newer models of smoke detector are set up to go off if they detect a certain level of heat, even without smoke.  The one in our apartment was definitely worried that I was trying to burn the building down simply by having the oven at 425 F...  Does yours have the same problem?  How do you get around it?
