Pfrommer makes no attempt at authenticity in this collection of Tenderfoot, Ranger Rider, and Bronco Buster recipes, though the dishes probably are in line with most American kids' idea of a fun meal. Black bean soup, Indian corn cakes, homemade baked beans, ""Fried Rice Mexicano,"" and two basic chiles are among the all-American Southwest standards included. But so are tomato sauce for spaghetti, ""prairie pizza"" on English muffin, chicken à la king, and dishes flavored with canned mushroom soup, dried onion soup, Worcestershire sauce, catsup, bottled taco sauce, and other processed concoctions that never saw a chuck wagon. No one learns to cook (or to taste) from a collection like this, though Marshall's drawings have more flavor and the package might rope in kids ready to take a step beyond canned and frozen dinners.
