DD really loves cottage cheese! And like Carolyn said, it's a really efficient way to get calcium into them.
For the record, legumes are everything in the bean and pea family, like lentils, chickpeas, any bean... I think they're "pulses" to you UK and Australian folk. DD really likes beans of all kinds-- she finger feeds them-- and she also likes a rice and lentil pilaf I make often for dinner, served with a cucumber-yogurt sauce (though she's not keen on the yougurt sauce yet). The pilaf is super easy; here's the recipe:
1 cup lentils (brown or green)
1 cup rice (you can use brown or white)
1-2 Tbsp olive oil
1 onion
1 tsp. salt
black pepper to taste
Soak the lentils (and the rice, if you're using brown rice) in enough water to cover plus 2 or three inches for 2 hours. About 20 minutes before you're ready to drain them, chop the onion and saute it in the olive oil until browned. When the onion is ready, add the drained lentils, rice, salt, pepper, and two cups of water. Bring to a boil, then cover and lower the heat to maintain a gentle simmer. Simmer for about 30 minutes, or until the rice and lentils are tender (remember that brown rice will still be chewy even when done) and all the water is absorbed. Turn off the heat and let stand for about 5 minutes, then fluff with a fork.
For the yogurt sauce, I just grate cucumber (and dice some nice tomatoes if I have them), chop a couple green onions (scallions), put them in a bowl, sprinkle with salt, then stir in enough plain yogurt (full-fat, low-fat, non-fat-- depending on what I have on hand and how indulgent I'm feeling) to make a nice saucy consistency. Then I taste it and add more salt if it needs it. I usually do this after I start the lentils soaking and then stick it in the fridge till dinner, so the flavors have time to blend.
The pilaf served with the sauce make a really great, filling, protein-rich dish. Lilah used to pick out all the lentils and eat them alone, but now she eats the whole thing with a spoon.
