Yum sounds delish! I might try your recipe.

Here is mine, it is similar except no cream (DH can't eat it) and has red lentils so super healthy and yum!

500g butternut pumpkin
1 potato
1/2 onion
1/4 cup red lentils, rinsed
1 chicken stock cube
2 cups water
1tbsp butter
1/4-1/2 cup milk

Fry onion in butter until just cooked. Add diced pumpkin, potato, water, stock cube and lentils. Stir and bring to boil. Simmer until vegetables are cooked and mixture has thickened. Blend. Re-heat and add milk until its at the thickness you want. Season with salt/pepper. I usually double this recipe and freeze some.
