Read the text «Comfort food’.Katie and Gilda talk about the food they eat to remember home and other comfort food they like.Katie: So what are three foods that you absolutely have to have that you can’t live without?Gilda: I would say that I could not live without arepa. It’s like my daily breakfast in Venezuela.Katie: What’s that?Gilda: Arepa is made of corn flour, and it looks like a hamburger. So you put anything you want inside and it’s very tasty. And I would say like 95 percent of Venezuelans eat arepas every day. Well, it’s kind of like a high-carb diet in my country. So I need rice also for lunch, and bread. Bread is another thing. In the afternoon, a piece of bread, sweet bread with coffee is kind of like mandatory.Katie: So lots and lots of carbs in your diet.Gilda: Yes. What about you? What about in England?Katie: Well, English breakfast is not the healthiest of breakfast. It’s like a big plate with fried eggs, fried sausages, hash browns, like hash potatoes, beans, just everything fried and everything delicious. And I would say that I can’t live without that, but if I ate it every day, then I would probably not be able to leave my house because I would be so, so fat. But it’s definitely a food that is in my top foods of all time. That’s probably my favorite. But recently, I’ve been eating lots of tofu. It’s breakfast.Gilda: Oh, okay.Katie: Yeah. So a little bit of tofu, a little bit of soy sauce just for breakfast, which is just – it’s a bit of a boring breakfast. But it’s really healthy, I guess. So I’ve been eating that a lot every day. So I probably can’t live without that recently. And also, pizza. Pizza.Gilda: Oh, pizza. Yes, very good.Katie: Pizza. I think everyone can’t live without pizza.Gilda: Yes.Katie: Pizza is the best. Pizza is definitely a food that I can’t live without.Gilda: Yeah, I try to have pizza probably once a week, I would say. Yeah.Katie: What’s your favorite topping?Gilda: That would be cheese.Katie: Cheese. Classic.Gilda: Definitely. Bacon.Katie: Cheese and bacon. Oh it sounds good.Gilda: Yes. Very, very tasty.Katie: Just cheese and bacon or anything else?Gilda: No, no. I’m going for anything actually but I will always need to have cheese and bacon on my pizza.Katie: Pizza is not pizza without cheese.Gilda: Yes. Yes.Katie: It has to have cheese.Gilda: So what else do you have? So you said tofu, pizza, what other food can you live without?Katie: Well, my grandma is part Italian. So we have lots of like pasta and lasagna in our family. So I try and eat – well, I try not to eat a lot of pasta because I’ll get really fat. But pasta is definitely something that I can’t live without. So good.Gilda: Yeah. Italian food is so good.Katie: Yeah. And again, lots of cheese.Gilda: Yeah. We also do a lot of lasagna but, well, we call it pasticho.Katie: Pasticho.Gilda: It’s a different name but it’s the same lasagna. And it’s also very tasty.Katie: So good.Gilda: Yeah. But high fat food.Katie: So like a real like comfort food, isn’t it? Lasagna.Gilda: Yeah. Yeah.Katie: So good. So what would you say is your comfort food?Gilda: My comfort food – that would be arepa, again. Yeah, definitely.Katie: You said you’re going to have lots of like fillings in that.Gilda: Yes. So my favorite would be black beans with cheese inside. It sounds a little bit like a mix up of things but it’s really, really tasty. We do eat a lot of black beans every day in Venezuela. It’s very common. What about you?Katie: My comfort food, I can’t eat it as much as I would like to these days but it’s probably my mom’s spaghetti Bolognese. So good. It’s so good, like lots of pasta, lots of tomato, lots of herbs, lots of cheese.Gilda: Sounds good.Katie: It’s amazing. I would like live with my parents if it meant I could have spaghetti Bolognese every day. So good. So tasty. I think it’s the best.Fill in the gaps:1. Gilda: No, no. I’m going for anything actually but I will always — ……. — and bacon on my pizza.2. So we have lots of like -…..- in our family.3. So good. It’s so good, like lots of pasta, -…..- , lots of herbs, lots of cheese.
