Oddly enough, one of my kids' favorite dishes is gorgonzola mashed potatoes! Weird kids! I will ask what they want for dinner when I'm on my way to the grocery, and they'll say "A big bowl of mashed potatoes, that good kind with the cheese."
I used a bag of red potatoes. I cleaned and halved them, put them in a pot, and filled the pot with water, enough to cover the potatoes. I boil the potatoes until they are soft (I check with a fork). Then I dump the water off, add a stick of butter, a tub of gorgonzola cheese and enough milk to be able to mash them. I never peel potatoes, and I always mash them by hand. It's always a rougher mashed potato, but it's the way I prefer them.
I used to buy pre-cooked, organic bacon with no preservatives that was already chopped up, but Whole Foods stopped carrying it (it's too convenient I guess, grrrr). So, I buy a small package of organic bacon with no preservatives and cook it while the potatoes are cooking. I let it cool before I chop it up.
Once the potatoes are mashed, then I throw the bacon in and stir it around. Seriously, my kids would eat it alone for dinner. I served it with chicken and green beans.
