First, prepare all three chutneys. I usually make them a day before. Or you can buy these chutneys from Indian grocery stores or buy online from amazon.
Now make batata vada. Or buy the frozen batata vada from the Indian grocery store. I prefer nanak brand, but other brands like swad, haldiram are also available.
Let’s start assembling. Take ladi pavs. Alternately, you can use hamburger buns.
Slit into half horizontally and keep the one side connected.
Spread green chutney both sides, followed by tamarind date chutney and dry garlic chutney.
Put the warm batata vada and using your fingers slightly mash it/press it.
and close the pav. Repeat the same for rest of the pav.
Serve as a snack with fried green chili on the side. If needed you can serve more chutneys on the side.
Notes
Method#2 (This is how I grew up eating in Ahmedabad, Gujarat)
Heat tava or pan on medium heat. Add a tablespoon of butter.
Once butter is melted, add 2-3 teaspoons of dry garlic chutney and mix.
Now put the slit ladi pav (inside part on tawa) on this mixture. Pav will soak up all the butter and chutney. Toast it for some time. Then remove it to a plate.
Proceed with the same assembling procedure. Apply green chutney, followed by tamarind date chutney. Now you can skip the garlic chutney since we already added while toasting pav.
