In a small bowl, mix the granulated garlic, salt and pepper together and rub all over and into the meat. Let stand 30 minutes at room temperature.
Prepare a charcoal grill for direct and indirect medium-high heat. Add the chips about 30 minutes before grilling the beef.
Setthe tri-tip over direct heat, fat-side up, and sear until nicely browned, about 10 minutes. Flip over and sear other side.
Move the tri-tip over the indirect-heat area, cover and grill until an instant-read thermometer inserted into the thickest part registers 130 degrees F, 20 to 30 minutes.
Transfer the meat to a cutting board and let rest at least 15 minutes. Slice the meat across the grain. Serve with Santa Maria Pinquito Bean Relish, Tomato Relish and Grilled French Bread.
Santa Maria Pinquito Bean Relish:
Heat a large saute pan over medium heat. Add the bacon and cook until golden brown and the fat has rendered. Remove the bacon with a slotted spoon to a plate lined with paper towels.
Add the poblano and onions to the bacon fat in the pan and cook until soft, 3 to 4 minutes. Add the beans and bacon and cook until warmed through. Season with kosher salt and freshly ground black pepper. Put into a serving bowl and top with cilantro or parsley leaves.
Preheat the grill for high direct heat.
Toss the tomatoes with the canola oil, season with salt and pepper and transfer to a grill basket. Grill, tossing once or twice, until charred on all sides. Remove the tomatoes to another bowl. Add the parsley or cilantro, olive oil, garlic paste, chiles and onions. Stir to combine and season with salt and pepper. Let sit at room temperature for at least 30 minutes before serving.
Grilled French Bread:
Mash the butter, garlic and some salt and pepper in a mortar and pestle.
Brush the cut side of the bread lightly with oil and season with salt and pepper. Grill the bread, cut-side down, until golden brown. Flip over and continue cooking for 30 seconds longer. Remove from the grill, slather with the garlic butter and cut each half into 4 pieces. Put the pieces on a platter and scatter parsley leaves over the top.
