Corn tortillas cradling whatever the market offers this week: summer squash one day, sweet peppers the next, always finished with ripe avocado and a bright salsa that lets the vegetables speak.
Go to the market first. Walk the stands without a list. What looks alive? What did the farmer pick this morning? That is your filling.
The vegetables here are suggestions, not requirements. Summer might bring you zucchini and sweet corn. Fall offers peppers and late tomatoes. Winter has roots and sturdy greens. The principle stays the same: choose what is at its peak, cook it simply, and wrap it in good corn tortillas.
I learned this way of cooking in Mexico, watching women at market stalls assemble tacos from whatever arrived that day. No recipes. No measuring. Just an understanding that perfect ingredients need almost nothing done to them. A hot pan, a little oil, salt. The vegetable does the rest.
Every meal is a meaningful choice. When you buy from the farmer who grew your squash, you are keeping that farm alive. The taco tastes better for it. Connection is an ingredient too.

Cut your market vegetables into pieces that will fit comfortably in a tortilla. Zucchini into half-moons, peppers into strips, corn left as kernels. The size matters less than consistency. Everything should cook at roughly the same rate.
Dice the tomatoes, keeping all their juice. Combine with the onion, minced pepper, and half the cilantro in a bowl. Add the lime juice and a generous pinch of salt. Stir once and taste. The tomatoes should be the star. Adjust salt until they sing. Set aside while you cook.
Heat a large cast iron or carbon steel pan over high heat until a drop of water dances across the surface. Add the olive oil, then the vegetables in a single layer. Do not stir. Let them char and blister, two to three minutes. Flip and cook another two minutes. Season with salt. The edges should be dark and caramelized, the centers still bright.
While vegetables rest, heat a dry comal or skillet over medium-high heat. Warm each tortilla for thirty seconds per side until pliable and showing light brown spots. Stack them in a clean kitchen towel to stay warm. Cold tortillas crack. Warm ones embrace their filling.
Halve the avocados and remove the pits. Slice each half into thin wedges while still in the skin, then scoop them out with a spoon. A ripe avocado yields easily. If you have to fight it, it is not ready.
Lay warm tortillas on a platter. Spoon the charred vegetables down the center of each. Add slices of avocado and a generous spoonful of fresh salsa. Scatter the remaining cilantro and crumbled cheese over the top. Serve immediately with lime wedges alongside.
