I love my pressure cooker! I'm not a good cook so I use it for simple recipes, nonetheless it is really useful. I make broth (meat broth for DH and me, veggie broth for my baby), steam cooked veggies or meat, tomato sauce, soups. Basically, everything that is liquid and takes hours to cook is ready in 30 minutes. You can search online for recipes, there are so many. Most important, pressure cookers are DH-proof: he tried to make broth and put too much water, when the cooker reached the boiling point it poured water all over the stove top (just like a regular pot) but didn't explode.
DM usually makes broth or soup in the morning and gets ready for work. When she is dressed and ready to leave, dinner is ready too.
