Feast on a Field Tex-Mex-inspired dip. Layer beans, shredded iceberg lettuce, diced tomatoes, and shredded Cheddar or Monterey Jack in a casserole dish. Smooth your favorite guacamole over the top. Spoon sour cream into a ziplock bag, snip off one corner, and pipe on field markings. Add pretzel-square goals. Serve the dip with tortilla chips.
