Not necessarily my favorites, but definitely things that are fond memory based dishes.
German Potato Salad - My paternal grandmother's was so yummy! It's about the only dish of hers that I've been able to replicate, but I never make it because DH and the kids don't like it. Still, so many fond memories with it from childhood.
Potato Kugel - This was something we'd only eat at Passover and often was only made on the night of the Seder. What's funny is that I'm pretty sure it was never more than the boxed mix they were making. So, it's nobody's special family recipe. Passover is probably my least favorite Judaic holiday due to the food restrictions and span of time. Potato kugel was one of the few things in the food lineup that I actually liked.
Macaroni & Cheese - DH and I have often debated about this just being a side dish vs. a full on meal. For me, it can be either/or. It's one of my great food loves. While my kids were never overly picky, DD15 had her moments. I remembered my mom telling me about my brother's picky eating phase and how mac & cheese was one of the only things he'd eat. The pediatrician gave her some tools to get past it, but also had her work with the mac since it's filling and the cheese is a good source of protein and calcium. So, I also used this to help the kids if anyone was having a picky moment.
