sauce for pizza ideas.

I think I'd spread a little enchilada sauce on the dough, layer on the meat, peppers and onions and then top with some cheddar cheese. 

Can't remember the brand right now, but I bought an off the shelf roasted poblano Alfredo sauce and put it on a pizza with chicken and my own roasted poblanos and it was awesome.

My go-to "sauce" is minced garlic and olive oil.  I heat it up just a tiny bit to infuse the olive oil with the garlic.  I make enough to brush all over the dough, edges too.  If I don't use garlic and olive oil, I use a basil pesto.  

Mtasker... This is the sauce I use on pizza. INGREDIENTS • 1 can (28 oz. / 828 g) crushed or ground to- matoes. You can also use canned whole Italian plum tomatoes, diced tomatoes, tomato puree, or tomato sauce. • 1⁄2 tablespoon (7.4 g) red wine vinegar • 1⁄4 (1.25 g) teaspoon ground black pepper • 1 teaspoon (5 g) dried basil (optional) • 1⁄2 teaspoon (2.5 g) dried oregano (optional) • 1⁄2 teaspoon (2.5 g) granulated garlic powder (optional) • water, as needed • salt, to taste PROCEDURE 1. If using crushed, ground, or tomato sauce or pu- ree, use a mixing bowl and whisk; if using whole or diced tomatoes, use a food processor. Add to- gether all the ingredients, except the water and salt, and whisk or process to make a smooth sauce. 2. Taste and adjust by adding enough water to make a slightly thick, easily spreadable sauce, as shown in the video. Adjust the salt, whisking it in, to taste. The sauce can be used immedi- ately, but it will thicken slightly as it sits. 3. Store any leftover sauce in a container with a lid. This sauce will keep for up to 10 days in the refrigerator or for three months in the freezer.

I agree with @Hog Heaven (I use basic garlic/crushed tomato pizza sauce on everything) that tomato sauce is best.  One addition I would do is maybe a dash or two of cumin to taste (on the pizza itself) to get it into the flavor profile for chicken fajitas.  Bon Appetit!

I have used pesto sauce, goat cheese, Boursin cheese, spiced up mayo, olive oil and garlic, and barbecue sauce or anything else you might use on a sandwich. Variety is the spice of life. ;;)

With chicken i only like bbq. My favorite is sweet baby rays. My go to pizza is ck sbr bbq sauce and red onion on a 50/50 whole wheat/bread flour mix. Little mozzarella cheese and good to go.
