sweat carrots, onions, and red pepper in some olive oil and some salt over medium low heat. Don't saute or color the veggies.

After 8-10 minutes or until veggies get soft, add the squash and minced garlic. Let the squash get some color and the garlic to release flavor. Then add seasoned meat. Stewing beef is fine, but I also like using london broil, flank, or plate. Even using top sirloin is good and cheap. Brown the meat on all sides, add oil if needed.

Then add water to cover. Add all the seasonings/herbs you want. Bay and thyme are usual ones to add. I've never tried basil in soups, but I don't think you'd go wrong. I'd save the chopped parsley until the end for a fresh flavor.

Other optional ingredients:

Sausage as someone else said.
Potatoes, corn, or peas (or really, an veggie you like)

Also, I'd refrain from using boxed or canned beef broth/stock. Boxed or canned chicken broth/stock tastes good, but boxed or canned beef broth/stock tastes bad.
