Here are two easy creamy soups that I make all the time. They take 5 minutes and you can control the sodium.
Creamy Tomato Soup
1/2 cup canned crushed tomatoes (I buy no sodium versions)
1/2 cup veggie broth
1/4 cup unsweetened soy milk
salt, pepper, Italian Seasoning
Combine all ingredients and heat through. Makes 1 serving. I like to add some frozen corn (not thawed) to it or eat it with some whole grain crackers.
Cream Pumpkin Soup
1/2 cup canned pumpkin
1/2 cup veggie broth
1/4 cup soy milk
salt, pumpkin spice
Same directions as above.
Not sure if you have access to cooking soups, but these are really good!
