Hi, I just tested (almost) all the recipes.
Method: used cheats to give sims the 'healthy eating' lifestyle and to learn pack recipes, then cooked my way through recipes that weren't fried, cakes or pies, 'starchy', or from the 'healthy meal' category the lifestyle unlocks. I didn't do all the Star wars or experimental recipes because the first five of each were all not healthy. Note, though, that my Sims had a well-stocked garden and some of these recipes may have only given them the 'healthy eating' buff because the ingredients were all fresh. And please excuse spelling, I was tabbing in and out to take notes.
Recipes that give the buff from the 'cook' menu: garden salad, tofu stir fry, balaeda, empanadas de verde, fruit salad, pan de muerto, arapa rello con perico, samosa, goi cuon, tacquitos, tajine, sweet and sour eggplant, ramen, pufferfish nigiri, pho, nigiri, lumpia, lobster roll, seafood cowder, egg rolls, pastel de pimito, areba de palion, vegetable dumplings, dango, curry, tofu tacos, onigiri, bhel puri, brochette, banh mi, egg ramen, beef ramen, watermelon salad, tomato wrapped veggie burrito, spinach wrapped veggie burrito, faux meat wellington, veggie slider
Recipes that give the buff from the 'gourmet' menu: Caesar salad, tamogo nigiri, vegetable tempura, caprese salad, tofu chicken saltimbocca, salmon maki roll, herb crusted salmon, spinach frittata, avocado maki roll, butternut squash soup, faux bacon wrapped asparagus, salmon nigiri, butternut gnocchi, tuna nigiri, faux lobster tortellini, meatless Montecristo
Recipes that give the buff from the 'bake' menu: whole wheat loaf, carrot bread, banana bread, sourdough loaf, potato bread, spinach and mushroom quiche, blueberry bagels
Recipes that give the buff from grilling on a BBQ: mushroom steak, camper stew, grilled chicken, elote, grilled plantain, grilled fruit, chicken chimichurri skewers, veggie burger, tofu dogs
And finally, two grand meals give the buff: grand breakfast, and tofurkey dinner.
I hope this helps simmers get the 'healthy eating' lifestyle while letting their Sims eat a variety of foods!
