Activate the yeast: Add the warm water (a digital thermometer is helpful to make sure it's between 120°-130°), yeast, and sugar to a large bowl. Allow to sit for 5–10 minutes, until the surface is foamy/frothy. If it doesn't get frothy, the yeast might be bad and it's best to toss that and start again. Make the dough: Add 1 cup flour, 3 Tbsp olive oil, and ¾ tsp salt. Stir until a shaggy dough forms.
Knead: Turn onto a lightly floured surface and knead for about 5–7 minutes, until smooth and elastic, adding more flour as needed. You can also knead it in a stand mixer for about 5 minutes.
Allow to rise: Place the dough in a large bowl, lightly oil the top, and cover with plastic wrap, and let rise somewhere warm for about 1 hour, or until doubled in size.
Preheat oven to 475° once ready to prepare pizza.
Roll dough: Punch the dough down and stretch/roll it into a 12–14-inch circle to fit your pizza pan. For a slightly braided-looking crust, I press my index finger at an angle into the edge of the dough, gently folding the dough over itself as I work around the crust. Then carefully transfer to the lightly oiled pizza pan.
Build pizza: Generously spread bbq sauce on pizza crust. Then evenly distribute onions, garlic, broccoli, jalapeño, and pineapple.
Bake pizza for 12-15 minutes and remove once the edges become golden brown, being careful not to overcook! Every oven is different, so keep a close eye on your pizza.
Finish and serve: Once pizza has finished cooking, remove from oven and transfer to a cutting board. Top with a generous handful of arugula, a little drizzle of bbq sauce, and an optional pinch of red pepper flakes.
