Ina Garten has all the bases covered when it comes to Tex-Mex entertaining. She makes a light and airy Tres Leches Cake with Berries and Make Ahead Whipped Cream, and her crowd-pleasing Pork Posole is a spicy, all-in-one main course piled high with fixings. Fiesta Corn and Avocado Salad is an easy first course that also works as a side dish or salsa. Finally, Ina raises her glass to cocktail hour with the fire and ice of frosty Jalapeno Margaritas, shaken like a pro!
