I would have a variety of accompaniments, such as salsa, chili, onions, shredded cheese, deli mustard. Also, if you want to WOW them then make some upscale sauces, such as these:
Romesco Sauce
1 cup of roasted red pepper, those are roasted and peeled
1/2 tsp of red pepper flakes for some heat
2 tbsp of sherry vinegar for a little acid
2 anchovy fillets for some salt and to give another dimension of flavor
1/2 cup of roasted almonds
4 cloves garlic
1/4 cup olive oil
Salt and pepper to taste
Slow cook garlic in oil until fragrant. Let cool. Put all ingredients in a food processor and blend until smooth. Let it ripen about a day.
Garlic Aioli
1 clove garlic
kosher salt
1 egg yolk
2 tsp lemon juice
1/2 cup olive oil
Crush/liquify garlic using salt as a vehicle. Add egg yolk and lemon juice. Wisk in olive oil until complete. Add other stuff as needed.
Orhers: Garam Masala (Indian Spice mixture) or Red or Green curry
